When Jack Teagarden arrived in New York in 1928, he quickly replaced Mole as the new role model for trombonists, with a more legato, blues-oriented approach. Mole, having started working for radio in 1927 (at WOR), changed his focus to working with NBC (1929–38). In 1938–40 he was a member of Paul Whiteman's orchestra, but his style by then had changed under the influence of Teagarden. In 1942–3 Mole played in Benny Goodman's orchestra, and between 1942–7 he led various dixieland bands. He worked in Chicago in 1947–54. Due to bad health, Mole played very sporadically during his last years.
