By 1977, Pete Townshend felt that maybe the Who were done. Punk rock was taking over London and he felt like a dinosaur, even though the Sex Pistols performed "Substitute" at almost all of their shows. One drunken night, Townshend bumped into Steve Jones and Paul Cook of the Pistols at a London pub, though Pete was so hammered he thought he was talking to Johnny Rotten. He told them he wanted to break the band up and when they urged him to reconsider, he felt even worse about the whole thing. He went home that night and wrote "Who Are You." Some of the lyrics were drawn from real life, like the time he woke up drunk in a Soho doorway and a police officer told him to go home. The song became their first big radio hit in a couple of years, though nowadays, most people think of it as the theme song to CSI.
