Close up: the carved eagle atop a flagpole in a shipyard. The camera pulls back as the eagle flies off and, while animal performers and seagulls impatient wait, picks up a baton and conducts a medley of patriotic songs. While the music plays, shipyard workers put together a battleship in this wartime Terrytoon.
Friz Freleng over at Leon Schlesinger's cartoon was the master of this synchronized musical cartoon, but Paul Terry's staff certainly knew how to do this sort of cartoon. From 1929 through 1932, that's what sound cartoons were: gags timed to a score, in this case still written by Terry's musical director, Philip Scheib back then and still written by and conducted by him. Techniques had advanced, but every studio did this sort of cartoon occasionally and this is a good example of the genre: no words, just music and well-executed gags. Sit back, enjoy the music and the fun.
