What is this sample from?

The one goes:

"Good music is what we want to hear"

"What do you mean, good music?"

"It's what we dance do, it's what our children will dance to. And if you don't want to play it, then take your records and go home!"

Seriously, no one knows this?

Bump. These are good questions I'd like the answer to. The problem is that no one ever reads this part of the board.

This is where the 'it's just music, what are you getting so crazy about?' sample comes from. Apparently a 1982 movie called Diner. I haven't seen it yet.
