I really enjoyed needapausebutton's quiz called Yes. THAT actor really sang in a movie. http://www.sporcle.com/games/needapausebutton/cmon-twasnt-nearly-as-bad-as-a-water-buffalo-was-it
I've tried create something similar though a lot of these songs aren't so good.
I apologize for forcing you to answer in order but a few stars feature more than once in the quiz. The ordered answering will be particularly annoying where three people sing together for one clip. Sorry.
