Don't know if I'll read the biography. Just not a reader. (other than 10 hours of news a day on the net, WTF?)
I heard Townshend in an interview a long long time ago describing the band meeting Keith Moon. Pete said he, Roger and John were mods then and when Moon showed up to try out for the open drummer's spot he looked like a rocker so they were thinking 'oh, s#!t, this isn't going to work.' Then Moon started tying his drum kit down and they really thought they had a wacko on their hands. Of course he played, blew their minds and the need to tie down his kit became obvious. And he was in!
My favorite Moonie story was when they were headed to the airport, and Keith said, “I gotta go back to the hotel, I forgot something.” So they go back, and when Keith returned they asked what it was that was so urgent, and Keith said, “I forgot to blow up the toilet.”
