The song tells the story of a recording session in Montreux, Switzerland, that didn’t go as planned.
At the time, Deep Purple had traveled to the lakeside town to record their sixth album, Machine Head, at the Montreux Casino. The venue was not only a renowned concert hall but also the main location for the Montreux Jazz Festival. To capture their new album’s sound, the band had rented the legendary Rolling Stones Mobile Studio (RSM)—a state-of-the-art recording truck owned by The Rolling Stones. They had just started laying down some initial tracks when disaster struck.
On December 4, 1971, Frank Zappa and the Mothers of Invention were performing at the casino. Around 90 minutes into their set, during King Kong, an audience member fired a flare gun into the venue’s wooden ceiling. Within moments, the building was engulfed in flames.

Deep Purple’s lead singer, Ian Gillan, was in the audience that night. Sitting in front of the culprit, he saw both flares as they were fired. As chaos erupted, the band fled to a nearby restaurant, where they watched helplessly as their planned recording venue was reduced to ashes. A thick layer of smoke drifted across Lake Geneva, framed by the distant Swiss Alps—a haunting image that later inspired bassist Roger Glover to come up with the now-iconic title, Smoke on the Water.
With their equipment trapped inside the burning casino and their accommodations destroyed, the band was forced out of the area. All they were left with was the vision of smoke swirling over the lake.
Rather than breaking down every detail in the lyrics, I’ll highlight one key event—the heroic actions of Claude Nobs, the “Funky Claude” mentioned in the song.
Claude Nobs, the founder and promoter of the Montreux Jazz Festival, played a crucial role that night. As the fire spread, several young concertgoers sought refuge inside the casino, believing they would be safe. However, Nobs—who had experience as a volunteer firefighter—recognized the danger and acted immediately, running in and out of the burning building to rescue them.
“Funky Claude was running in and out, pulling kids out the ground.”
Nobs didn’t just save lives that night; he also helped Deep Purple regroup after the disaster, securing a new location for them to record. Thanks to his efforts, the band was able to complete Machine Head—and the events of that fateful night were immortalized in Smoke on the Water, one of the greatest rock anthems of all time.
Zdenek Spicka, a Czechoslovakian national residing in Switzerland at the time, was accused of starting the devastating fire. According to a local newspaper article published later that month, Spicka allegedly fired several capsules followed by a small flare into the venue’s ceiling, igniting a blaze that ultimately consumed the entire building. He fled the scene immediately, and despite a police ‘Wanted’ operation being launched, he was never found.

One thing that does surprise me though, is that Frank Zappa didn’t write a song about the event
