You can find the winner's list here, but what was more important were these two musical numbers:
Oscars Opening Number - Hugh Jackman
Musicals Are Back - Hugh Jackman, Beyoncé, Zac Efron, Vanessa Hudgens, Amanda Seyfried, Dominic Cooper
Update: I didn't say anything about the performances when I posted the videos but maybe I should. The opening number was great. I didn't care much for the recession theme, but it was well done and wonderfully performed. Hats off to Mr. Jackman. And who would have thought Anne Hathaway had that voice in her? The standing ovations were well-deserved.
Now regarding the musical medley my enthusiasm is starting to decrease when I get to it. Hugh Jackman and Beyonce are quite alright, she's quite a bit of a diva actually, but the other two couples don't really fit in. Their performance is weak and they look more like filling, I don't know why they called them at all. Well, actually I do know why, but they shouldn't have made that compromise for publicity's sake.
