A skinny, arty guitarist with an appetite for destruction. A mic-twirling singer who liked a fight. A bearish, sardonic bassist. Chaos personified on drums. Four west London lads who somehow coalesced into The Who. Packed with electric live footage and expansive commentary from Roger Daltrey and Pete Townshend, this is a comprehensive portrait of one of rock's greatest and loudest bands, from post-World War II childhood through mod hits and rock operas, epic excesses and internal battles, the deaths of Keith Moon and John Entwistle, and the recent return to action of Daltrey and Townshend - sometime antagonists and fiercely loyal friends who, far from dying before they got old, have aged as gracefully as anyone in their generation.
