Deacon wrote a number of Queen's hit singles, including "You're My Best Friend", "Spread Your Wings", "I Want to Break Free", and the band's biggest selling single in the United States, "Another One Bites the Dust", as well as a number of album tracks. He also played electric and acoustic guitars on several albums and, to a lesser extent, keyboards, synthesizers, programming and drums. He very occasionally provided backing vocals during live shows. Behind the scenes, he was also involved in the group's financial management and electrical equipment design.
