Singing to make us happy

No matter how many times I watch it, Sister Act, that film about a lounge singer on the run who goes into a convent under the Witness Protection Scheme, never fails to make me giggle, sing and laugh. Are there any films that you love? This is definitely one of mine.

And on that note (pun fully intended), a friend has sent this clip to me. http://www.youtube.com/watch?feature=player_embedded&v=R0Fpl67p5qk. Isn't singing an amazing thing!
