The Who were one of the best known bands at Woodstock. Like Jefferson Airplane, who they played just ahead of, they were scheduled to headline the Saturday night performances, but didn’t get to perform until the pre-dawn hours Sunday. Their set consisted almost entirely of the rock opera Tommy (not counting the interlude when Pete Townshend clocked Abbie Hoffman in the head with his guitar after Hoffman stormed the stage and commandeered the microphone), but they ended the set with the title track from their 1965 debut album, My Generation.
