While flipping through records at a flea market, Bart and Lisa discover an album by the Be Sharps, a barbershop quartet comprised of Homer, Barney, Apu and Principal Skinner. As Homer recounts the story, it is clear that the Be Sharps saga is a classic tale of four men who rise to the top of the entertainment business, only to find that the demands of fame and success destroy their friendships and strain their love for their art. After telling his kids all about the band, Homer gets nostalgic and the Be Sharps reunite for one last concert on the roof of Moe's Tavern.
