A very Musical Episode, in which Homer starts a band (again) while Will Forte (from Saturday Night Live, Sit Down, Shut Up, The Cleveland Show, and Conan) guest stars as the owner of King Toot's (the music instrument store next to Moe's Tavern) who returns with an ax to grind against Moe. Sammy Hagar also guest stars as himself.
- Continuity Nod:
- When Homer breaks into the band's dressing room, a picture on the wall shows him, Barney, Skinner, and Apu during their time as the Be Sharps singing band.
- When Sprawl-Mart is shown, the slogan underneath it says, "Still not a parody of Walmart", calling back to its appearance in "On a Clear Day, I Can't See My Sister".
- Continuity Snarl: This episode seems to ignore the fact that Homer has been repeatedly shown to be a talented musician.
- Driven by Envy: Homer makes it clear to Lisa that this is how he feels about Apu leaving Covercraft for Sungazer.
- Insistent Terminology: When Homer is accused of being jealous of Apu, he says he's not jealous but envious. After Homer explains the difference between "jealous" and "envious", Lisa consults her dictionary and realizes he's right.
- Singing Voice Dissonance: Discussed when Apu demonstrates his singing abilities for Homer's band:Dr. Hibbert: Why is your voice different when you sing?
Apu: It is because of all the years I spent at the Kwik-E-Mart where classic rock anthems were piped in on a never-ending loop. The endless repetition drove many clerks to madness. The only way to maintain my sanity was to sing along until it seemed like our voices were one.
