What are some of the Classical influences of Queen?

I'm really interested in this particular aspect. With Freddie being somewhat Classically trained in piano and certainly taking an interest, I was just wondering what influences you can hear from their music from the Classical/Baroque etc?

Love Of My Life has some classical-inspired piano runs. Not piano related but Brian had great interest in George Formby's music, which inspired Good Company, as well as his ukulele/banjo playing in general.
