What song was the British rock band Queen's debut single?

"Keep Yourself Alive" is a song by British rock band Queen. Written by guitarist Brian May, it is the opening track on the band's eponymous debut album Queen (1973). It was released as Queen's first single along with "Son and Daughter" as the B-side. "Keep Yourself Alive" was largely ignored upon its release and failed to chart on either side of the Atlantic. It was also re-released as the non-album B-side of Lily of the Valley in 1974.

In 2008, Rolling Stone rated the song 31st on its list of "The 100 Greatest Guitar Songs of All Time".

According to Mark Hodkinson, author of Queen: The Early Years, "Keep Yourself Alive" was conceived on acoustic guitars during Queen's practice sessions at Imperial College and the garden at Ferry Road in 1970. At the time Queen had not yet found a permanent bassist; the group consisted of guitarist Brian May, singer Freddie Mercury and drummer Roger Taylor. In a radio special about their 1977 album News of the World, May said he had penned the lyrics thinking of them as ironic and tongue-in-cheek, but their sense was completely changed when Freddie Mercury sang them.
