1975 Knebworth festival poster
1975 was the year Pink Floyd appeared, complete with World War II spitfires flying low behind the stage as they started their set.
Roy Harper appeared backstage on a horse and was most upset when,due to the 16' drop,he wasn't allowed to ride it on to the stage.
Quadrophonic sound was installed, probably the first time at any outdoor event.
Booked after the poster was printed, the late Graham Chapman, of Monty Python's Flying Circus made various silly appearances throughout the day.
The complete programme included Pink Floyd, the Steve Miller Band, Captain Beefheart's Magic Band, Roy Harper and Linda Lewis.
The poster was designed by Hipgnosis.
