English rock band Queen. It was originally released on the album A Night at the Opera in 1975. Brian May wrote the song and sings lead vocals on its skiffle-like arrangement, featuring three- and four-part harmony vocals — including passages of falsetto during the middle bridge section, which culminate in a high-A note sung by Roger Taylor (May commented in 2005 that Taylor actually refused to sing the note he wanted, so he got him to sing a lower note then used varispeed to up the pitch).
