Best music/dance scenes in films?

[annandale]

I love a good 'let's do the show right here' kind of moment.

I'd forgotten this scuzzy yet magnificent chunk of the original Fame -

Yy echt love Westside Story.

Also so many to mention from Oliver! Consider Yourself, Ompah-pah-pah, I'd do anything, Pick a Pocket or Two, Be back soon, Who will Buy?

I always cry at the end of the film when Fagin and the Artful Dodger do their jig with the silhouette of St. Paul's in the background - sheer brilliance.

I am a bit of a fan.

Every Sperm is Sacred. From Monty Python's The Meaning Of Life. Apparently they blew a large chunk of the budget on it
