Brett Smiley (September 25, 1955 – January 8, 2016) was an Americansinger-songwriter who was active in the UK during the glam rock era of the early 1970s. Smiley released one single, "Va Va Va Voom," and made an appearance on the Russell Harty television show, where he performed the song "Space Ace".
In 1974, Smiley—who, at the time, was managed and produced by Rolling Stones manager Andrew Loog Oldham—recorded an album, Breathlessly Brett. The album, which included the songs "Va Va Va Voom" and "Space Ace", remained unreleased until 2004, when RPM Records included it as part of its Lipsmackin' 70s collection.
Smiley also starred as the Prince, in the 1977 American erotic musical comedy Cinderella.
In 2004, rock biographer Nina Antonia published a book about Smiley, The Prettiest Star: Whatever Happened to Brett Smiley.
Smiley still performed occasionally until 2015 in New York City, and was recording songs for a new CD. He died on January 8, 2016, after a lengthy battle with HIV and hepatitis.
