This is where the Montreux Jazz Festival was held in the summer, but during the rest of the year other concerts were organised there, under the name of Montreux Pop, and people came from far away to attend them.
I was 14 years old the first time I went in August 1970. There were two concerts on the program, with three bands that were supposed to play twice each. I remember seeing Black Sabbath and Taste, but Cactus the third band had been blocked at the border and only played the second show which I was unable to attend.
Taste was Rory Galagher's power trio, and their shows were recorded, resulting in the record that is called Live Taste.
The bassist for Cactus was Tim Bogert, also bassist for Vanilla Fudge and Beck, Bogert & Appice, and I had the opportunity to meet him in 1981, as he was teaching at the Musicians Institute in Los Angeles where I was studying.

That day in August 1970, Claude Nobs was on stage to announce the next concerts and that's when he told us that Jimi Hendrix was coming before the end of the year. Explosion of excitement in the audience. It was the time when the triple LP and the film from Woodstock were released, as well as the Band of Gypsys album.
Unfortunately Jimi passed away on September 18, which really affected me because I loved him so much and was looking forward to finally seeing him.

The summer of 1970 was an incredible time for musical discovery.
I remember other concerts I saw in the Casino venue, Deep Purple, Procol Harum, Jethro Tull and Santana, between 1970 and 1971. I also remember missing bands I really liked like Led Zeppelin and Chicago, or Santana's first concert.

So on December 4, 1971, I had just turned 16, I was already familiar with the place, but I had no idea that I was going to enter this hall for the last time.
At that time, there were no chairs, it was not yet the fashion of the standing concerts, and the public sat on the floor, sometimes on a cushion or on a jacket rolled in a ball, which was my case.

That day, there was an unusual decoration on the ceiling. It was probably planned for the end of the year celebrations, and it seems to me that it was a tropical decoration, with or interlacing reeds or lianas, with paper or polystyrene flowers perhaps. What is certain is that all this material was dangerously flammable, as the future has proven!

I think the ceiling was made of concrete and wouldn't normally have caught fire if it hadn't been for those temporary decorations that you can't see in any of the photos.

What can be seen above the stage must have been acoustic panels. There are photos of these panels falling to the ground in the furnace.

At the time I didn't know all the songs played, I understood very little English and in this version of the Mothers there was a lot of dialogue.

I remember Zappa’s entrance on stage with a coffee pot in hand. He was wearing a long coat that, at the time, seemed like a bathrobe to me. I liked this quirky side, even though everyone knows that Zappa was a very intelligent man.

You can see the coffee pot on the Orange amplifier head to Zappa’s right. The coat is casually draped over the black PA column, which I will talk about later.

I remember when Frank announced Call Any Vegetable by saying "this is a song about vegetables", the audience started to applaud, but all the lights turned green instantly and the applause was cut short by the surprise felt by the audience. When you listen to the recording of the concert, you can hear it clearly.

So here we are, after about an hour and 20 minutes, the band has just played the melody from King Kong, and leaves the stage to Don Preston for a synthesizer solo. Don fiddles with the oscillators of his Mini-Moog, it is a coincidence, but he produces sounds that may sound a bit like an alarm.

I'm sitting in the center, about 2/3 of the way across the room. The sound of the synth suddenly stops, and I see flames in the ceiling 10 or 15 meters away from me on the right. Mark Vollman says "Fire! Arthur Brown in person!" Then Zappa says "Calmly go towards the exits, ladies & gentlemen".

I didn't see, but it is believed that a guy fired a flare gun towards the ceiling. At the beginning, the fire is very small, I think that it will be put out quickly and that the concert will continue. I drag a little to go out, I hesitate to leave my jacket rolled up to keep my space on the floor, well in front of the stage!
People go out quickly and very calmly, and the firemen and guards on duty get a little upset to get us out faster.

The fire grows quite quickly, and people open the curtains that hide the windows on either side of the stage. I see some people grab chairs to break the glass.
I see a little blood, someone has been injured, but it seems to be minor.
Once the windows are broken, we feel a big draught rushing in the room, which drives away the smoke, but also fuels the fire.

I decide to go out that way, the ground must be about three meters down, there is a ledge I hang from and I drop into the grass without any problem.

A friend of mine, whom I didn't know at the time, told me this:

"Alain, I was there too! It is with a WEM speaker cabinet sound system that was on stage that I grabbed with other people to break the windows, which enabled us to escape by jumping in the grass below...
I remember very well Zappa very calmly telling the audience to get out without panicking. I think that his calmness allowed a quick and safe evacuation.
In the rush, I had left a small Moroccan bag in which I had put my things and an Afghan coat (made of sheepskin, very trendy at that time) and especially my documents. Before jumping, I went back on my steps to take back my things which were exactly where I had put them.
Coming out of the smoke, a fireman, visibly surprised to find me there in front of him kindly asked me to leave... "quickly because it's very dangerous to stay there!"
I had the impression that Don Preston's "moog" was still making weird sounds on the deserted stage... So I grabbed my stuff and quickly walked out through the broken windows. It seemed to me that a few moments later, the ceiling collapsed."

This speaker cabinet is clearly visible on the right side of the stage, and on one of the previous pictures we can see its three letters logo in the upper right corner, a little blurred but very characteristic. According to Frank Zappa, the Orange amp went the same way.

The next picture of the WEM logo is not from the concert.

The stage was very low, at most three feet, and that's what made it easy for another friend of mine to climb it and end up walking down a backstage staircase with Zappa.

Another guy managed to reach out and grab Frank's wah-wah pedal. Being a guitarist, he still uses it today. Appart from a cowbell mentioned by FZ in an interview, it may be the only instrument to have survived the fire.

After jumping from the window, I go around the building to find my friends, and I see people coming out of the main door with Zappa posters in their hands.
I can't imagine that the whole building is going to burn down in a very short time, so I go back in through the main door and come out with some posters.

I had this poster already, as it had appeared folded in eight in a Swiss German magazine called POP. The poster distributed at the concert was the same size, but it was not folded. It didn't have the POP logo on it, but the paper was also very thin.

I may still have a copy of the folded poster, but I think it's in eight pieces.
I found the following picture on the net.

This door must have been on the side of the building, the main entrance was larger.

The following photo shows the corresponding spot in the back of the stage.
I think I hung from the ledge and jumped in the area to the left of the bushes.
