David Allen Stewart was born on September 9, 1952 in Sunderland, Tyne & Wear. He formed the band The Tourists with his lover Annie Lennox. When their relationship ended they went on to form the popular band Eurythmics. Eurythmics proved to be one of the most consistent and creative pop-rock duos of the 1980s. When Eurythmics dissolved in 1990, Stewart immediately released a solo album with the Spiritual Cowboys. Throughout the 90's, Stewart released albums, including a solo album. In 1999,Eurythmics reunited to release Peace. Stewart continues to be involved in a variety of projects, recently relocating to the United States.

Recently Stewart has written a musical, Barbarella, which is based on the 1968 movie and which premiered in Vienna, Austria on March 11, 2004.

He normally credits himself as David A. Stewart, partly to avoid confusion with another musician known as Dave Stewart.

On the 4th April 2005 a Bechstein grand piano owned by Stewart was auctioned by Bonhams for £3,600. The piano had been used by stars including Bob Dylan and Sir Paul McCartney.
