Queen was blessed with three members who had excellent voices. Freddie Mercury was, obviously, the primary lead singer, but Brian May and Roger Taylor sang on their shares of songs, as well.
Songs on which May sang lead included '39, Some Day One Day, and Good Company. Songs on which Taylor sang lead included I’m In Love With My Car, Drowse, and Rock It (Prime Jive).
When Trevor Rabin joined Yes, the album on which the band was working on (90125) wasn’t going to be labeled as a Yes album, since it didn’t have enough members of the band. Vocalist Jon Anderson wasn’t involved in the project, and Rabin was slated to act as both lead vocalist and guitarist. Anderson joined the project partway through, and took over most of the lead vocals, though Rabin still sings co-lead on several tracks, including Leave It (Rabin sings the first verse).
