Arguably in The Who, it was Roger Daltrey and Pete Townshend who kept things in check - while the virtuosic John Entwistle and unpredictable Keith Moon played bass and drums like lead instruments. Still, there are few basslines more memorable and brilliant than Entwistle's run on 'My Generation', and indeed he stamped his personality over most of The Who's output, inspiring generations to see the bass guitar as something much more than a four-stringed pace-maker. Moon's fill-heavy, characterful drumming - whilst often seeming to teetering on the edge of a trainwreck, always, always came back in when it was meant to and made The Who an incredibly exciting band. Both were true, one-of-a-kind musicians.
