Who Wrote/Sang It?

When I listen to the Beatles I can't always tell who is singing. That is to say I think my Beatles chops are developed enough to tell the differences, but I'm never confident enough to know for sure. I'm not even positive when it's Ringo singing. Similarly, when I hear a song that is particularly good I assume John wrote it; A particularly ill-fitting or strange song was most likely written by George. You get the point.

Anyway, I don't need to guess anymore, with this helpful wikipedia page.

I was shocked to find that George wrote a lot--if not most--of my least favorite Beatles songs.
