Carl Carlson celebrates his birthday with friends at Moe's. Homer voluntarily gives his car keys to Moe and walks home, and winds up in a holding cell with Cletus.
In the holding cell, Officer Eddie provides Cletus with an acoustic guitar. Cletus sings a song that thoroughly impresses Homer, who then resolves to become an upstanding citizen and help Cletus's musical career.
Homer gets Cletus a gig at a dive bar, and from there his Cletus becomes a star.
Tropes:
- The Cameo: Mary Spuckler appears among her siblings.
- Celebrity Paradox: Cletus says that Elin looks different from when she was in Finding Nemo. Albert Brooks (Slick manager) played Marlin in that film.
- Credits Gag: As with Vice (2018), this episode has premature end credits at the end of Act I. Cletus stops the premature credits, and gives himself a whittling credit.
- Continuity Nod: Homer mentions the time he managed a successful songstress.
- A Day in the Limelight: For Cletus.
- No Celebrities Were Harmed: Elin Degenerous, a parody of Ellen DeGeneres.
- Oddly Small Organization, lampshaded: The Springfield Police Department. Walking home from Moe's, Homer sees a cop who is not Chief Wiggum, Sergeant Lou nor Officer Eddie. Homer wonders out loud "We have other cops in this town?"
- Shout-Out:
- To A Star Is Born (1954).
- The title itself is this to Guitar Hero, except with Yokels.
- Take That!: An Expy of Ellen DeGeneres is portrayed as an overly hostile and abusive control freak.
