This cartoon, the first in Walter Lantz's Swing Symphony series, is built around a performance of the title song, an original by Felix Bernard and Ray Klages about army life. It's set at "Camp Pain," situated within the Toyland Army section of the Toy Department of the "Maybe So Dept. Store" and features the toy soldiers and animals on the shelves coming to life and joining in to do all the orchestral and vocal parts. (imdb comments)
