The Smashing Pumpkins- “1979” and “Perfect”.
People said “Perfect” sounded so much like “1979” that the music video was intentionally made to be a sequel to the latter.
EDIT: The Smashing Pumpkins are my favorite band. If you can find a copy of Greatest Hits Video Collection (1991–2000) (a DVD collection of music videos and other goodies; acted as a companion to Rotten Apples), I recommend it. There is extensive audio commentary on the videos. For example, Stéphane Sednaoui who directed “Today”, claimed to had never listen to the song before the first day of filming. “1979” in particular had master tapes got destroyed after someone left them on the roof of their car, so the entire video had to be re-shot. “Perfect” commentary, Corgan makes the connection to the similarities with “1979”; all but one of the original teenage actors from the first video returned. There is a short film version of “Try” that featured a different ending to “Try, Try, Try”. A few live recordings are included, among them “Fuck You (An Ode to No One)” from the final Metro show when they broke up and “Geek USA” (a special mix that utilized maximum volume on the audio system).
“The Beginning Is the End Is the Beginning” is an alternate version.
EDIT: The tracks on the single for “The End Is the Beginning Is the End” are all alternate versions.
