Ruby Tuesday was recorded in Olympic Studios in November, 1966 and was released in January, 1967 on the B-side of Let's Spend The Night Together. It spent twelve weeks in both the U.K. and U.S. charts, reaching the number one spot in the U.S.

In her autobiography, Marianne Faithfull refers to Ruby Tuesday as Jones' ...swan song... and recalls the recording session when Ruby Tuesday was conceived: Brian...played a folkish, nursery rhyme melody on the recorder. It was nothing more than a wispy tune, but it caught Keith's attention...he had heard a riff and went at it like a dog with a bone...it was really Brian and Keith's song...I'd noticed that this song had taken on an almost desperate significance for Brian. This collaboration between Keith and him was to be the last, and perhaps he could sense that. He knew it was one of the best things he'd ever done...
