Harper punctuated the song with dramatic chorus cries of "Batman, Batman, Batman!" Vedder is in good company: both the Jam, and Vedder's heroes in the Who have covered the song.

Rather than keeping it in the family Vedder uploaded the track to SoundCloud. It's not Harper's first credit on the site--eight months ago Vedder uploaded a track called "The Traveler," co-written and performed with his daughter.
