Montreux is renowned in rock circles not just for it's famous Jazz Festival, which is an annual pilgrimage for music fans the world over... On 7th December 1971, Frank Zappa and The Mothers of Invention played a concert in the casino theatre that was part of the Montreux Entertainment Complex. A Swiss fan fired a flare gun, the ceiling caught fire, and the casino was consequently completely destroyed. Deep Purple were also in town to begin recording an album the following day, and they watched the casino burn from their hotel across Lake Geneva, and immortalised the moment in the song "Smoke On The Water". The lyrics mention "funky Claude", which refers to Claude Nobs, the director of the Montreux Jazz Festival, who helped some of the audience to escape the fire.
