Pink Floyd

The Pink Floyd were part of the Lanch Arts festival 1972 who played at the Coventry Locarno along with Chuck Berry (who recorded My Ding  a Long there) and Slade. Pink Floyd played early version of tracks which were later on the Dark Side of the Moon in a more developed form and the programme was then Eclipse before it was changed to Darkside of the Moon.
