"Flash" is a song by British rock band Queen. Written by guitarist Brian May, "Flash" is the theme song of the 1980 film Flash Gordon. The soundtrack released to coincide with the film contained only the music composed and performed by Queen.
There are two versions of the song. The album version ("Flash's Theme") is in fact the start to the movie, with all the dialogue from the first scene. The single version features dialogue cut from various parts of the movie, most memorably, Brian Blessed's character exclaiming "Gordon's alive?!" This version was also included on the Greatest Hits compilation from 1981.
Flash is sung as a duet between Freddie Mercury and Brian May, with Roger Taylor adding the high harmonies. May plays all of the instruments except for the rhythm section. He used an Imperial Bösendorfer Grand Piano (with 97 keys instead of 88, having an extra octave on the low range), Oberheim OBX synth (which he plays in the video) and his homemade Red Special electric guitar.
Contrary to connections made in popular culture, and despite the song's title, it bears no relation to the DC Comics character of the same name.
