Quote related to 'Bohemian Rhapsody' from 'A Night At The Opera'

[who came up with the idea for the vocal harmonies] We always were keen on that kind of thing. That was something which we wanted to do from the beginning. We wanted to be a group that could do the heaviness of hard rock, but also have harmonies swooping around all over the place. We thought there was some real power and emotion in that combination.

Brian May; Guitar Player magazine, January, 1983
