At aprox 15:10 , when they are clipping in Stanley Cubrick there is a song called, and I quote; "Title Music From A Clockwork Orange (From Purcell's Music For The Funeral Of Quenn Mary)" by Wendy Carlos.
after the kid does up his clamps and hammond tells the you that "the kids pretty fast considering he doesnt have brakes" they played a short clip, at two A.M. last night i figured out what it was "howard shore - lord of the rings the two towers - the king of the golden hall" just a piece of it but thats what it was.
In case anyone is curious... The song playing while the Bowler Wildcat is racing the kid on the all terrain skateboard down the hill (approx. 40:50 - 41:50) is James Horner from the Aliens soundtrack. I believe it's track 11 entitled "Ripley's Rescue" (in the movie, it is playing when Ripley is driving the APC into the colony complex to rescue the marines).
