Despite several key lineup changes, Pink Floyd are one of the most enduring English bands.
The psychedelic rockers were known as "Pink Floyd Sound" when they formed in 1965 - named after Georgia bluesmen Pink Anderson and Floyd Council. Soon after, they dropped the "Sound" from their name.
Legend has it that when they met representatives of their record label, EMI, they were asked: "Which one of you is Pink?"
The band's debut album, The Piper At The Gates Of Dawn, was released in 1967.
In 1968, founding member Syd Barrett, who had a problem with LSD, left the group, becoming a recluse. He was replaced by David Gilmour, a friend of singer Roger Waters.
