I have been asked to do a Guitar demo in assembly. I don't think anything of a 'classical' nature would go down too well so does any know of any books which have some popular film music or similar that have been arranged for Classical Guitar.

Hotair, you'd be surprised...son has a thick wad of fanletters from the last time he played classical guitar at a school camp (mind you, only half the letters were about music...the other half concerned his choice of wardrobe! )

If you can pick things up by ear, consider some game music - film themes with published classical guitar scores are likely to be too old for your classmates to know!
