The two man comedy dance act of Stump and Stumpy, big in nightclubs, radio, television and films in the 40s and 50s, was a tremendous influence on many other performers, including Martin and Lewis, and Larry Storch, who had a night club act prior to his best known role as Corporal Agarn on F Troop. Originally consisting of James “Stump” Cross and Eddie “Stumpy” Hartman, the team started out on the all-black vaudeville circuits before debuting at the Apollo Theater (where they became a staple for decades) in 1938. Harold Cromer (himself already a show biz veteran) replaced Eddie Hartman as “Stumpy” in the late 40s. Harold continued performing long after Cross dropped out — his last movie was 1984’s The Cotton Club. You can see the team at the peak of their hilarious form here.
