A Swingin' Affair is an album recorded in 1962 by saxophonist Dexter Gordon, recorded two days after Go! with the same line-up, but not released for two years.
The album was recorded at Van Gelder Studio, Englewood Cliffs, New Jersey, on August 29, 1962. Gordon's quartet contained pianist Sonny Clark, bassist Butch Warren, and drummer Billy Higgins. Of the six compositions, three are standards, two were written by Gordon, and one was contributed by Warren.
A Swingin' Affair was released in early October 1964. The Penguin Guide to Jazz picked "You Stepped Out of a Dream" as the album's highlight, but described the session as a "not altogether riveting date."
