Last night, Amy Winehouse took the stage with Mark Ronson to sing their cover of the Zutons' "Valerie." (How fucking adorbz is Ronson's mod look?) Amy's performances in the middle of her downward spiral were a hot mess to say the least, but after seeing the clip above as well as her performance at the Grammys last week, we're wondering if maybe she's awkward because her (relative) sobriety makes it so that she's hyper-aware of her surroundings. (Why does she dance like she's gotta go pee pee? For someone who's so into soul, she doesn't really have moves.) Later, Amy returned to the stage to sing "Love Is a Losing Game" and, of course, gave a shout out to "Blake Incarcerated". (That's his new name now. We're sick of typing out Fielder-Civil.) After the jump, check out a few of our favorite Amy performances, pre-crack.
