The Who were one year and three months into their Tommy tour when they played their second engagement at the Isle of Wight Festival. As in 1969, they played most of their famous rock opera, which by this time was quite familiar to the festival crowd. Huge spotlights bathed the audience of between 600,000 and 700,000 attendees (according to the Guinness Book of Records) and as The Who's tour manager John Woolf recalls, attracted "every moth and flying nocturnal animal on the island". The Who started their set at 2:00 A.M.
