In 1964 Pitt signed his first record deal using the stage name, "Ebony Keyes", with Parlophone, releasing two songs, "Brother Joe" and "Under the Apple Tree".
In 1968, Pitt signed to the United Artists Records, and at the suggestion of an A&R executive, changed his stage name from Ebony Keyes to "Lee Vanderbilt".
In the same year Vanderbilt was asked to represent the United Kingdom at the Gibraltar World Music Festival, where he won gold and bronze medals with two songs of his own composition, "How Shall I Know" and "A Woman's Way".
The first commercially successful artist signed to Biddu's production company was Carl Douglas, who in 1974 released his well-known disco hit "Kung Fu Fighting".
[2] Carl Douglas also recorded three songs written by Lee Vanderbilt, "I Don't Care What the People Say" (Biddu-Vanderbilt), "Stand Up For Love" and "Never Had This Dream Before", all three of which appeared on his Kung Fu Fighter album in 1974.
The album was produced by Biddu with arrangement performed by the likes of Gerry Shury, Chris Karan, Rebop Kwaku Baah, Michael Moran.
In addition to releasing his own album, working with artists as a session singer and percussionist and collaborating with Biddu and the other artists signed to Biddu's production company, in the 1970s, Lee Vanderbilt performed a song, written by George Barrie and Sammy Cahn, called "The Night Has Many Eyes", for the 1973 film Night Watch starring Elizabeth Taylor and Laurence Harvey.
