"I can't believe I went to Juilliard for this."

Actually the ending piece that wins the duel is not Steve Vai's composition really, it's Paganini. The piece is ironic in some ways - Steve Vai represents Paganini and the classical school whilst Ralph represents Robert Johnson, yet Ralph wins by playing a Paganini piece that he must have learned in Juilliard.

Ralph does a great job at fake guitar playing in this movie, by the way. I wonder if he actually turned out to be a decent player after all the training he must have gone through.
