The 2001 film:
El Tango de Roxanne! Even people who hate the film will usually agree that this is just a goddamn cool scene.
The Come What May finale also qualifies, specially when Zidler punches the Duke in the face.
Sparkling Diamonds. Never let it be said that Satine doesn't know how to make an entrance.

The Show Must Go On. Come on, it was originally performed by fucking Queen, people!
Also, the Elephant Love Medley. Forget the song title.
"Bolero", the extraordinarily epic end credits music.
Your Song. That's All, Folks!
Lady. Fucking. Marmalade.
Zidler punching the Duke in the face right at the end of Spectacular Spectacular.
