"2001: A Space Odyssey" opening with music performed by student orchestra

I haven't laughed so hard in ages. Here's the opening of "2001: A Space Odyssey" with music performed by a student orchestra. They're terrible, horribly offkey.
The music is by the Portsmouth Sinfonia. (For more information, check out their Wikipedia page.)
