The band went through a number of name changes including The Abdabs, The Architectural Abdabs (due to the fact Waters and Mason met on an architecture degree) and The Screaming Abdabs but were unable to keep band members and the group broke up in 1965 when Metcalfe and Noble left the band to write singles for Chad and Jeremy including "A Summer Song". Keith Noble now works as a drama teacher at Brantwood School, Sheffield. Two new members joined the band to augment these leaving members:
Klose, a classmate of Syd Barrett and David Gilmour from Cambridge, was brought in to replace Metcalfe and, as a consequence, Waters switched to bass. Chris Dennis, who was the new lead vocalist was soon replaced by Barrett. Shortly after, Waters, Wright, Mason, Barrett and Klose, formed the Tea Set, which soon became The Pink Floyd Sound and later, simply Pink Floyd. It was soon after when what was the earliest incarnation of Pink Floyd made their first recordings. In late 1964, the band recorded four songs on a demo: "Lucy Leave", "King Bee", "Double O Bo", and "Butterfly".
