St. Thomas is a calypso-inflected jazz composition credited to Sonny Rollins, though it derives from traditional sources rather than being an original melody. Rollins' mother, who had roots in the U.S. Virgin Islands, sang the tune to him as a child. The melody traces back to the traditional English song The Lincolnshire Poacher, which traveled through the folk process to become a nursery rhyme in the Caribbean, also known in the Bahamas as Sponger Money. Pianist Randy Weston actually recorded the melody first, releasing it as Fire Down There on his 1955 album Get Happy, but it was Rollins' arrangement on Saxophone Colossus in 1956 that cemented the tune in the jazz canon. Recorded when Rollins was just 25 years old, that session established both the composition and its composer as central figures in jazz. The tune's Caribbean rhythmic feel set it apart from the swing and bebop idioms that dominated the era, and its accessible, memorable melody made it an immediate jam session staple. Despite its apparent simplicity, the composition has proven remarkably versatile as a vehicle for improvisation, particularly for thematic development. Notable recordings include the intimate guitar-and-bass duo version by Jim Hall and Ron Carter on Alone Together (1972) and a big band arrangement by Gene Glover for the Dallas Original Jazz Orchestra. Vocalist Mark Murphy recorded a version titled Down St. Thomas Way with lyrics by Ray Passman and Herb Wasserman. The tune was also selected to represent jazz in the Encarta digital encyclopedia, a testament to its status as one of the most widely recognized compositions in the repertoire.
