After 70 minutes of playing, Keith slumped over his drums. A cold shower and shot of cortisone later, and he was back on stage... where he quickly passed out again. Noticing the conspicuous lack of bitchin' drum solos, Pete Townsend asked if there was anyone in the crowd who could play drums.
Scot Halpin, 19, hadn't played the drums for nearly a year. Nonetheless he bravely stepped up and... stood by while his friend screamed, "He can play!" The concert promoter took notice, and, after a shot of brandy (with a conspicuous lack of tranquillizer chaser) Scot found himself on stage, behind the drums, playing for The Who.
