Jack Black and the rest of the The Super Mario Galaxy Movie cast debuted a new song that wasn’t used in the film. In a recent appearance on The Tonight Show Starring Jimmy Fallon, the actor, dressed as the Koopa King, strummed his guitar and performed “The Ballad of Mario.” Chris Pratt, Anya Taylor-Joy, Brie Larson, Charlie Day, Glen Powell and Donald Glover provided backup vocals.
