James "Trummy" Young (January 12, 1912 – September 10, 1984)[1] was an American trombonist in the swing era. He established himself as a star during his 12 years performing with Louis Armstrong in Armstrong's All Stars. He had one hit with his version of "Margie", which he played and sang with Jimmie Lunceford's orchestra in 1937.[2] During his years with Armstrong, Young modified his playing to fit Armstrong's approach to jazz.
