Pink Floyd formed in 1964 from earlier bands whose names included Sigma 6, T-Set, Megadeaths, The Screaming Abdabs, The Architectural Abdabs, and The Abdabs. The band was again renamed The Pink Floyd Sound and then simply The Pink Floyd (after two blues musicians, Pink Anderson and Floyd Council). The definite article was dropped by the time their debut album was released.
Pink Floyd originally consisted of Bob Klose (lead guitar), Syd Barrett (vocals, rhythm guitar), Richard Wright (keyboards, vocals), Roger Waters (bass, vocals) and Nick Mason (drums). They covered rhythm and blues staples such as 'Louie, Louie'. As Barrett started writing tunes more influenced by American surf music, psychedelic rock, and British whimsy, humour and literature, the heavily jazz-oriented Klose departed and left a rather stable foursome. The band formed Blackhill Enterprises, a six-way business partnership with their managers, Peter Jenner and Andrew King.
