I'm quite suprised that no-one has asked the question already but for those who may be interested the beautiful music from the BBC adverts for Euro 2004 (past masters one) is taken from Romeo and Juliet and is a song called Balcony Scene by Craig Armstrong. IT gives me goosebumps everytime I hear it and is a stunning piece of inspiring music.
It can be downloaded through Kazza of anyone wants it.
