Smiles

A male vocal quartet is singing on stage. A spotlight close up shows their eyeballs shaking hands. The bouncing ball begins. Later, back on stage, one guy plays a series of instruments. Another leans out of a window and plays the written score as if the letters of the lyrics were the keys on a piano.

This series of animated cartoons- sometimes including bits of live action- took popular songs of the day and combined the popular "bouncing ball" following the lyrics in an effort for audience singalongs.
