Which Queen member wrote the song 'You're My Best Friend'?

Which Queen member wrote the song “You’re My Best Friend”? John Deacon wrote it. The Queen bassist composed the song for his wife, Veronica Tetzlaff, and it became one of his most recognisable contributions to the band’s catalogue.

The song first appeared on Queen’s 1975 album A Night at the Opera and was released as a single in 1976, backed by “’39.” Deacon also played the Wurlitzer electric piano heard prominently on the recording, alongside his bass guitar. Freddie Mercury sang the lead vocal.

A common mix-up is to credit Mercury because he sings the song, or Brian May because of his prominent role in Queen’s songwriting and guitar arrangements. However, the official songwriting credit belongs to Deacon. The single reached number seven in the UK and helped establish his knack for concise, melodic pop songs within Queen’s more theatrical rock sound.
