The Be Sharps
Homer's barbershop quartet in the "Homer's Barbershop Quartet" (first aired 30 Sept. 1993) episode of The Simpsons. They hit the charts in the summer of 1985, win a Grammy with the song "Baby on Board," and manage to release two albums (Meet The Be Sharps and Bigger Than Jesus) before breaking up due to group tensions and the evergreen "creative differences."
They were originally Homer Simpson, Principal Seymour Skinner, Apu Nahasapeemapetilon and Police Chief Clancy Wiggum. But the lineup that hit the big time was Homer Simpson, Principal Seymour Skinner, Barney Gumble and Apu D'Beaumarchais.
Real barbershop group The Dapper Dans provided some of the singing voices of the group.
