On August 21st, 1976, Lynyrd Skynyrd took the stage at Knebworth Park in England as part of a daylong festival that also included among others Todd Rundgren's Utopia, 10cc and headliners The Rolling Stones. With Ronnie Van Zandt's all-in vocals and their famed triple guitar attack featuring Gary Rossington, Allen Collins and Steve Gaines, Lynyrd Skynyrd delivered an electric performance in front of a crowd estimated between 150,000 and 200,000, which has gone down as one of the band's greatest performances.
