マザーズ・オブ・インヴェンション
Kaylan and Volman left The Mothers of Invention after an irate fan pushed Zappa into the orchestra pit at the Rainbow Theatre in London during a concert on December 10th, 1971, seriously injuring him. With Zappa confined to a wheelchair and unable to sing or play guitar for a year, The Mothers of Invention were on hiatus so Kaylan and Volman set out on their own as Flo &amp; Eddie, never officially returning to the Mothers.
