Some of A Day at the Races is a baroque masterpiece - mainly the stuff that I didn't write - and I feel very proud of it. One of my favourite tracks is The Millionaire Waltz, which was recently used in a ballet by the legendary French choreographer Maurice Bejart. It's a great choice because it is so rich in invention. It staggers me, the stuff that Freddie put into it. The bass lines are phenomenal, and listening to what I did on it I can't even remember how I arrived at all that stuff. Sometimes there are ten different things going on at once - different guitars, with different sounds, going different places.
