This performance of Lauryn Hill's classic "Doo Wop (That Thing)" on Fallon last night was obviously recorded back when she was on the show playing for Bob Marley week. But when you've got a performance as impressive as this one, you can't burn this off on your website: You've got to play this on the show. The only disappointing this is that this isn't with the Roots, who would have crushed this. But maybe since Hill's band can keep up with her rushing through the verses faster than the original, she kept them. Either way, this is can't miss right here.
