There is some controversy over whether fellow ex-Yes member, keyboardist Tony Kaye, who appeared on the first Flash album, was actually an "official" member of the group, or merely a guest. The confusion stems from the fact that the record company listed Kaye alongside the other members of the group on the back cover. Interviews with all the parties confirm that, though Kaye was invited to join, he declined, and should have been cited as a guest on the first album. He went on to found Badger in 1972. Other potential keyboard players were approached or auditioned at the time, including Ian McDonald (formerly of King Crimson), Rick Wakeman (soon to join Yes) and Patrick Moraz (also a future member of Yes), but eventually the band decided to carry on as a keyboard-less quartet, with Carter handling the occasional synthesizer part.
