Put on Your Old Gray Bonnet (1929) ** 1/2 (out of 4)The Fleischer Studio produced a number of these animated short films where the "bouncing ball" would have audience members singing together. The story here is pretty simple as a group of animals are warming up with their instruments before going into the title song. If you're familiar with these shorts then you know the plots really aren't anything special. With that said, these were meant to be fun for a crowd of people and to get them to sing together. On that level this here was mildly entertaining and there's no question that the animation itself was good. This won't have much appeal today but it's worth watching for film buffs.
