Following his departure from Bath , Bannister founded the Knebworth Festival in 1974 and ran what would be the first of seven consecutive festivals there . These festivals were headlined by The Allman Brothers in 1974 , Pink Floyd in 1975 , The Rolling Stones and Lynyrd Skynyrd in 1976 , Genesis in June 1978 , Frank Zappa and Peter Gabriel in September 1978 , and Led Zeppelin in 1979 ( two concerts ) . Bannister 's concert promotion company , known as Tredoar , was forced into liquidation in the early 1980s due to a financial dispute with the management of Led Zeppelin following the 1979 festival
