Trivia: During the episode, Skinner reveals that his POW number was 24601. This is the same as Sideshow Bob's inmate number and takes after the prisoner number of Jean Valjean in Les Misérables. That same prisoner number was also Hank Jennings' in "Twin Peaks".Kara
Trivia: Some Beatles references in this Beatle mirroring episode: more obviously the rooftop concert, Abbey Road-esque second album cover, the Japanese Artist (Yoko) and the song Number 8 sounding like a dumbed down version of Revolution Nine. Probably less obviously is the closing line, 'I Hope We passed the audition' is the end of the rooftop concert and "Let It Be" album. On the back of the Be Sharps album is the four members in similar poses (hand positions and with Homer with his back to camera) to the inner sleeve of "Sgt. Pepper". The greeting at the JFK airport, their managers 'Boys, you've just recorded your first number one', mimicking George Martin on hearing "Please, Please Me", the cries of "Wiggum forever, Barney Never" echo the "Pete Best Forever, Ringo Never". The list goes on.and on.and on.
