Brian May's "Il colosso"

Hello,

I've a question: anyone knows what pieces of classic music are used in this song? I can recognize the final part of Tchaikovsky's Overture 1812 (which was used by Cozy Powell in his drum solos too), but I can't recognize any other (for example, the beginning of the song).

Thank you very much and sorry for my bad Engish... ;-)

guess there's some Richard Wagner in there as well, but I might be wrong

Yeah, it's true, Ride of the valkyries :-).

But there are still more pieces. I'm almost sure the beginning of the song is one of them.

Thanks!

There are also the "Figaro"-quote: "my hero, my hero, my hero..."
