Video: Elvis Costello X The Roots "Fire" Live on Jimmy Fallon

Like I said, you don't have to be a Bruce Springsteen fan to appreciate the amazing live performances that #SpringsteenWeek has brought out of the baddest band in late night over on Jimmy Fallon. The maddest yet may be this take of The Roots backing punky legend Elvis Costello on a cover of "Fire"--over the rhythm section from the Staple Singers' classic "I'll Take You There." Which as Questlove recently discovered, is actually the riddim section of "Liquidator" by reggae outfit The Harry J All-Stars. Leave it to a brit to school a Philly beat fanatic on who used what drums first. LargeUp, Mr. Costello! While we're larging bout yourself, check Fallon (as Neil Young, below) and a special guest cover LMFAO. Oh, you will be.
