Who Really Sings 'The Joker'? Direct Proof from Vinyl Credits to Movie Tracks
If the song you are thinking of features wah-pedal slide guitar, a whistling hook, and references to "the gangster of love," the vocalist is Steve Miller. Recorded at Capitol Studios in Los Angeles in late 1973, the track served as the title piece for the Steve Miller Band's eighth studio album.
The liner notes on classic rock vinyl credits confirm Steve Miller as lead vocalist, rhythm guitarist, and primary producer. Miller constructed the lyrics by pulling lines from his own back catalog. He lifted phrases directly from his 1969 track "Space Cowboy," his 1968 cut "Gangster of Love," and his 1972 song "Enter Maurice." Miller also credited Eddie Curtis and Ahmet Ertegun because he interpolated the line "lovey dovey" from The Clovers' 1954 R&B song "Lovey Dovey."
The single proved to be a commercial juggernaut. It climbed to No. 1 on the Billboard Hot 100 in early 1974. Sixteen years later, after soundtracking a high-profile 1990 European television commercial for Levi's 501 jeans, the exact same master recording hit No. 1 on the UK Singles Chart. Miller's mellow, melodic delivery remains one of the most recognizable vocal takes in FM radio history.
