This cartoon builds and builds and builds, and when it's over you're almost worn out. It features an immensely-talented monkey. He's the chimp part of the organ grinder's act. The while grinder sings, the little monkey climbs the tenement street windows to collect a coin here and there from an appreciative female audience. Some of the ways he gets to the windows are clever.
However, the animated short really clicks into high gear about halfway through when the chimp begins to perform for a bunch of little kids in the street. The little animal turns out to be a great one-man band, amazing dancer, and celebrity impersonator (Harpo Mark, Laure & Hardy).
Outside of a little cat-abuse, the film has harmless slapstick gags as the monkey's shenanigans cause havoc in the streets while the band blasts out "42nd Street" at a faster-and-faster pace as the cartoon accelerates to a frenetic pace by the end.
This was a bonus feature from the "Warner Night At The Movies" from the DVD feature film, "The Mayor Of Hell." It's definitely worth checking out.
