"The music for the song has been around for a few years. There are some demos I made with Joey and David a few years ago in Los Angeles, related to a film idea that still has yet to see the light of day, although work on the music continued," Frontman Black Francis says of Bagboy. "It's pretty simple, kind of a blues-based, two-note kind of thing, really."

Despite how it sounds, Black Francis has confirmed it's not Deal singing on the track, but his long-time collaborator Jeremy Dubs. The band have said they're not working on a new album � although Dubs last year told Examiner.com he'd recorded a "batch of demos" with Francis, explaining: "I got to play drums, bass, keyboards, sing backing vocals and do lots of other super-fun stuff. It was a dream come true."
