Questlove and “Captain” Kirk Douglas were back as ‘Black Simon and Garfunkel’ Wednesday night and their performance of Lorde's Royals could well be the very best cover version yet.

The Roots’ musicians regularly appeared as their folk alter egos on Jimmy Fallon's Late Night and thankfully they've carried forward their act to the comedian’s new gig on the Tonight Show.

Black Simon and Garfunkel have previously harnessed their talent to perform cover versions of Pitbull and Ke$ha's Timber, Macklemore and Ryan Lewis’ Thrift Shop and Katy Perry's Roar.
