They consisted of Jim Campbell (bass, singing for Seymour Skinner), Shelby Grimm (lead tenor, singing for Chief Wiggum and Barney Gumble), Mike Economou (tenor, singing for Apu), and Dan Jordan (baritone, singing for Homer Simpson). Though their singing was mixed with regular voice actors singing. They also helped co-write the song Baby on Board.
