"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 number three.
Notable renditions have been recorded by fellow Texans, country crooners Jim Reeves and Ray Price.
