Willie Nelson and Jimmy Kimmel Duet on SXSW Love Song

Jimmy Kimmel wrapped up his week of South by Southwest shows in Austin last night with a love song to the Texas capital: "To Austin, I Can't Love You More." But shortly into the performance, Kimmel, dressed in a cowboy hat and bolo tie, dramatically stopped and asked for a little help. Enter Willie Nelson, who walked onstage to a standing ovation. Prior to the showstopping performance, Nelson joined Kimmel for an interview, in which he announced his new album: a record of duets with longtime friend and collaborator Merle Haggard. Titled Django & Jimmy, the album will be released later this spring, with first single "It's All Going to Pot" out April 20th — the very pot-friendly date of 4/20. Django & Jimmy also includes the pair's musical tribute to Johnny Cash.
