Of course, if they're gonna go disco, The Roots might do better to go old school. Patti LaBelle isn't really disco, though. Rather, she possesses a range that crate-diggers like Questlove can definitely appreciate. Before LaBelle was "Lady Marmalade," the soul singer rocked the fuck out as The Rolling Stones' opener.

Even at her current advanced age, LaBelle would still ladle a heaping helping of stank all over anything The Roots threw her way. And it doesn't hurt that she's as much a Philly institution as Rocky, or at least the Delfonics.
