The mall manager is played by Marcus Vaughn, a friend of Trey Parker and Matt Stone and appeared in their film, Orgazmo.
In this episode's commentary, the creators remarked this was the first episode where they really started to use the method of "straight-storytelling." Before this, almost all episodes had A-stories, B-stories, C-stories, etc. that would all come together in the end. In this episode, the creators said they learned that an episode can be about just one thing, with character's side stories all reacting to the main idea.
Randy's fit of rage, ending in him smashing the glass doors of the living room cabinet and shouting "No! Nooo!!" is very similar to a scene in Star Trek: First Contact, where Captain Picard does the same. In fact, Randy's voice changes from Parker's to a sampling of Patrick Stewart's voice from the film.
During the audition scene, the piano accompanist is a character Schroeder from the comic strip and cartoon Peanuts.
During Randy's flashback the girlfriend he says goodbye to appears to be Sharon.
Matt and Trey were going to call their band 'Fingerbang', but instead called it 'DVDA'.
Cartman says that Wendy has, "huge knockers"; this is one episode after she kissed him in "Chef Goes Nanners". Cartman seems to be trying to impress Wendy.
Randy was in a boy band called the Ghetto Avenue Boys, an obvious parody of The Backstreet Boys. Fingerbang is a parody of NSYNC. This aspect of his past foreshadows his attempts at fame, most notably in "You're Getting Old" and the season 18 Lorde storyline.
During Cartman's first dream of Fingerbang's fame, a girl with reddish orange hair and pigtails is duplicated throughout the crowd several times.
During Cartman's dream, right after Cartman's solo, Stan and Kyle both say "bang bang" but the voice heard is that of Cartman.
Kenny is killed after being crushed by a mall lift/elevator. Knowing that Fingerbang can't go on without a fifth member, Randy replaces him.
Before Stan and Randy Marsh head to the mall a visitor can be seen in above Randy and Sharon Marsh's beds as one of the pillars under the bridge.
