Stephen Thanks Elvis For Providing The Soundtrack To A Tender Moment With His Mom

Stephen kicks off his three part interview with rock legend Elvis Costello with a special "thank you" for the artist whose music played a key role in a wonderful and bittersweet moment Stephen shared with his mother near the end of her life. Stick around to watch these old pals talk about music, life and more in parts two and three of the interview, before Elvis and his band The Imposters take the stage to perform a song from their new album, "The Boy Named If." #Colbert #Elvis #ElvisCostello
