Roy Flynn is an English former music manager. He managed The Speakeasy Club in 1960s London, in which capacity he associated with and befriended rock stars of the era like Keith Moon and Jimi Hendrix. He began managing bands, and after one night when Yes was called in at the last minute to replace Sly and the Family Stone at a 1968 gig, Flynn was so impressed with the band he offered to manage them.
