Keith Moon was best known as a member of the Who, but he was far more than that, even within the context of his role within the group. Moon, with his manic, lunatic side, and his life of excessive drinking, partying, and other indulgences, probably represented the youthful, zany side of rock & roll, as well as its self-destructive side, better than anyone else on the planet. In that sense, he was the soul of the Who, as much as Pete Townshend was its brain and Roger Daltrey was its heart; and, along with John Entwistle, Moon was at the core of its sound, and not just for his drumming per se. He played the skins with the kind of wild abandon that most trained musicians before him, not knowing any better, would have described as lunatic, in the worst sense of the word, and he lived his life with just about that same degree of intensity (even once running himself over with his own car). But more than the drumming itself, it was the lunacy that he brought to the personality mix of the four members that kept their music and their playing, not to mention their image, on the cutting edge of youth, even as they all moved into their thirties and tried to get more serious about music.
