Jack Teagarden

Weldon Leo "Jack" Teagarden (August 20, 1905 – January 15, 1964) was an American jazz trombonist and singer. According to critic Scott Yanow of Allmusic, Teagarden was the preeminent American jazz trombone player before the bebop era of the 1940s and "one of the best jazz singers too". Teagarden's early career was as a sideman with the likes of Paul Whiteman and lifelong friend Louis Armstrong.
