Thanks to WattsupWatts for the request. She's probably going to yell at me in the comments for getting it wrong.

Mick
Roger Daltrey, because they're both the front man. Roger is known for swinging his mic around while Mick is known for resembling someone having a seizure on stage, so they're both known for their stage presence.

Keith
Keith Moon because they have the same name and they're both pretty wild. I mean, no ones as wild as Keith (Moon.) it's just physically not possible... But still.

Brian
Pete Townshend, because they're both misunderstood. There's no need to elaborate further.

Charlie
John Entwistle, because they're both pretty chill, cool guys who are often overlooked.

Bill
John Entwistle, because they're both creepy bass players who liked young girls.
