On December 4, 1971, Zappa suffered his first of two serious setbacks. While performing at [[Montreux Casino|Casino de Montreux]] in Switzerland, the Mothers' equipment was destroyed when a flare set off by an audience member started a fire that burned down the casino.<ref name="Occhiogrosso"/>{{rp|112–115}} [[Deep Purple]] were in the audience that night, and would immortalize the event on their classic 1972 song "[[Smoke on the Water]]". A recording of the incident and immediate aftermath can be heard on the bootleg album ''Swiss Cheese/Fire'', released legally as part of Zappa's ''[[Beat the Boots II]]'' box set. After losing $50,000 ({{Inflation|US|50000|1971|r=-3|fmt=eq}}) worth of equipment and a week's break, the Mothers played at the [[Rainbow Theatre]], London, with rented gear. During the encore, an audience member, jealous because of his girlfriend's infatuation with Zappa, pushed him off the stage and into the concrete-floored orchestra pit.<ref name="Reed">{{cite web |last1=Reed |first1=Ryan |title=When Frank Zappa Was Pushed Offstage in London |url=http://ultimateclassicrock.com/41-years-ago-frank-zappa-pushed-off-stage-in-london/ |website=Ultimate Classic Rock |access-date=January 29, 2019 |date=December 10, 2015}}</ref> The band thought Zappa had been killed—he had suffered serious fractures, head trauma and injuries to his back, leg, and neck, as well as a crushed [[larynx]], which ultimately caused his voice to drop a [[Major third|third]] after healing.<ref name="Occhiogrosso"/>{{rp|112–115}} A recording of the whole concert, including the attack, was released on the posthumous album ''[[The Mothers 1971]]'' in 2022.

After the attack, Zappa needed to use a wheelchair for an extended period; this made touring impossible for over half a year. Upon return to the stage in September 1972, Zappa was still wearing a leg brace, had a noticeable limp and could not stand for very long while on stage. Zappa noted that one leg healed "shorter than the other" (a reference later found in the lyrics of songs "Zomby Woof" and "[[Dancin' Fool]]"), resulting in chronic back pain.<ref name="Occhiogrosso"/>{{rp|112–115}} Meanwhile, the Mothers were left in limbo and eventually formed the core of Flo and Eddie's band as they set out on their own.
