In this cartoon short, Mickey Mouse is running an opera house--though it's really more like a cabaret where various song and dance numbers are played for the audience. As for Mickey, he has assorted duties--such as pushing huge customers (like the hippo) into the show--one way or another.
I agree with one of the other reviewers who said that this cartoon has minimal plot compared to other early Mickey Mouse cartoons. Despite this, it still is quite fun and stands up reasonably well today. However, I think it's best if seen by someone who appreciates classic cartoons and doesn't mind that this one is in black & white and has, compared with today, relatively simple animation. Compared to other early Mickey cartoons, however, this one is certainly not among the better ones and is most average.
