The theme to the picture is drummers...unless they didn't have a drummer/the drummer was already used before.

^^^LOL, I saw the "unless they didn't have a drummer" part but I didn't see the last part of the sentence at first and I was thinking, "WTF, Brian Wilson wasn't the drummer!". Then I was smart and read the rest of the sentence and realized you hadn't made a mistake...I did XD

Haha :D What should my next theme be? Lead guitarists?

Lead guitarists would be good. I'd love to see what George Harrison and Carl Wilson icons you use (assuming that neither one of them get voted out this round, of course!). Then maybe bass players after that?

Uh huh. Pfft like The Beatles could get voted out. Haha.
