The Magnificent Seven Monkeys?
Lost Weekend at Bernie’s. And no, you didn’t get mine. While ‘Seven Brides’ was a musical, they weren’t musicians, were they?
Hee. You focused on the apocalypse, and Sampiro focused on the musicians, but neither of you included both. 
Keep guessin’!
Missed this one before. The Outlaw Josey W(h)ales of August.
I’ll even throw in the Western remake for bonus points…
The Magnificent Seven String Samurai!

Children of a Lesser Godzilla.
A tougher-than-tough Hong Kong Cop goes up against a vicious gang, culminating in a game of cat-and-mouse in the hallways and air duts of a skyscraper.
Dancing kids is pretty much my idea of the apocalypse.

And It’s not **Romeo Must Die ** as the other half of mine… I’ve never actually seen that. Hmmm. Maybe I can think of a better clue…
-
To Kill The MockingBirdCage
-
Every Which Way But Footloose

Hmmm…

You got 2 and 3, but I had something different in mind for 1.
The Three Musketeers of the Sun
Here’s another one:
Classic documentary about the rise of a fascist candy-factory owner.
