His live TV debut on SNL has gone down as maybe the most famous moment in late night music history. But the decades that followed were just as surprising, rebellious, and at times baffling. It's ELVIS COSTELLO week!

Joining the show is comedian, actor, and Elvis Costello historian Connor Ratliff (Dead Eyes, Tiny Dinos, The George Lucas Talk Show)! Connor does his best to walk the guys through the overwhelming twists and turns of Elvis' 50 year career. We of course begin with Elvis and the Attractions act of rebellion on SNL in 1977. Joan Rivers has Elvis on The Tonight Show in 1984 and lots of tissues are involved. The 90s bring collaborations with string quartets and Burt Bacharach, plus a very public feud with bassist Bruce Thomas that plays out on late night. And we end with Elvis as the elder statesman fronting The Roots on Fallon in 2009.
