What movie is this from? I mean, I am pretty sure it is from a movie, because seriously, there is no audience and they always had audiences... so if you know, please tell. Thanks.

YouTube - Sam Butera-Chantilly Lace

:D

Here are their imdb pages.

Louis Prima

Sam Butera

And here's a list of everything they are credited in together:

IMDb joint venture search

D'oh! The joint venture link doesn't work!

Go to the bottom of either of their pages and there's a box, "Find where this name is credited with another" and enter the other name. You'll get a list.

Well actually, they starred in over three, and they were of the same quality, so it's a little vague =(
