"Roly Poly" is a humorous Western swing standard written by Fred Rose in 1946. In the song, Roly Poly is a very active boy who eats continuously to keep his strength up. Each verse ends with: Roly Poly, daddy's little fatty,Bet he's gonna be a man someday. "Roly Poly" was first recorded by Bob Wills and His Texas Playboys in 1946, staying on the charts for 18 weeks and reaching #3. It has been recorded by many Western swing bands since. Notable renditions have been recorded by fellow Texans, country crooners Jim Reeves and Ray Price. Chuck Berry's "Roly Poly" is a different song.
