Entwistle was almost always the stoic on stage regardless of whatever riot might be going on with the rest of the gang. A real contrast, especially compared to Pete with his windmills and amazing leaps and scissor-kicks and spins (all while wearing Doc Martens), and Daltrey whipping his microphone around at Mach 1.
Of course, Townshend's latest book provides more stories that Entwistle wasn't quite so quiet off stage-- he was usually the one accompanying Moon on his carousals. 

Hmmm, makes no sense. Your friend plays in a band and is always dissed? Maybe he's in the wrong band. The story of how The Who made the rehearsal the song is a testament to John.
Maybe your friend isn't a good musician?
