From Queen’s 1976 masterpiece album A Day at the Races. “Somebody To Love” is famous for its amazing lead and background vocals. The group delivered a “choir” into the track by just multi-tracking the voices of guitarist Brian May, lead vocalist Freddie Mercury, and drummer Roger Taylor. It was actually Taylor who contributed the highest of the notes on the track. Produced by Queen themselves, the track was recorded at The Manor, Sarm East, in Wessex, U.K.
