Listen to "Ballin' The Jack," a previously unreleased track from Harry Nilsson and Dr. John

A massive, 17-disc retrospective of Harry Nilsson’s RCA Records years drops next Tuesday, and in preparation, The A.V. Club has the exclusive premiere of one of the box set’s tracks. “Ballin’ The Jack” features both Nilsson and Dr. John and was recorded in Hollywood on July 28, 1976. The track has never been released, and wasn’t even really mixed until this past March.

If this track and all of Nilsson’s other work strikes your fancy, pre-order the whole set here. Check out a Vine of the fancy set’s unboxing below, too.
