"Suzanne" by Matthew Fisher.
Mathew left Procol Harum after playing organ on their first three albums (their good ones), and got a solo deal with RCA. "Suzanne" is the opening track on his first album (Journey's End), which like all the other songs on the album he wrote and sings. The album features accompaniment by only a bassist and drummer---no guitars to get in the way---with the exception of some strings and brass on a couple of tracks. I love the album, but know no one else who has heard it.
