Plot While browsing at the Springfield Swap Meet, Bart & Lisa come across a record with Homer's face on it. Homer reveals that he used to be in a barbershop quartet back in 1985 with Apu, Principal Skinner and Chief Wiggum. They used to perform at Moe's and other places. They got recognized by a record agent, who becomes their manager. He persuades them to replace Wiggum with Barney, and the group decides to call themselves the "Be Sharps." Homer writes a song called "Baby On Board" which is a huge hit, and the group win a Grammy. However, Marge misses Homer as he is on the road all the time, and there is friction between the group. After five and a half weeks, the band split up. Homer finishes telling the story to the kids, and sends them to bed. Feeling nostalgic, he organizes a get-together of the group and they sing on the rooftop of Moe's Tavern.
