1975 rock song from the band Queen, famous for its music video, which includes a sequence of the four band members' faces lit up in darkness, arranged in a diamond pattern.
(Although the oft-parodied image, with the bottom figure crossing their arms in an X, is actually taken from the cover of their album Queen II.)
There is also a 2018 movie of the same name, which dramatizes the group from their formation to their famous performance at Live Aid in 1985.
