Pink Floyd recorded debut album Piper At The Gates Of Dawn in London's Abbey Road Studios, while the Fab Four worked on their iconic 1967 album in the next room.

But Floyd didn't hear it until they were touring the UK as part of a package tour headed by Jimi Hendrix and also featuring The Move, The Nice, Amen Corner and Eire Apparent.

Waters tells KLCS: "I remember pulling the car over into a lay-by, and we sat and listened. Somebody played the whole thing on the radio. I remember sitting in this old beat-up Zephyr 4, just completely stunned.
