There seem to be a lot of cartoons with player pianos and organ
grinders. That is because they are inherently funny.
Bugs Bunny was an organ grinder near what looked like Central Park
West, where his monkey would scramble up to windowsills to collect
coins from apartment dwellers. (Through the usual series of odd
incidents, a gorilla took over the monkey's job.)

are the words and punchings of a piano roll. I believe that the song
was 'Mother Macree.' I was maybe ten years old when this appeared on
"Disneyland" or one of the other Disney TV shows, and I didn't recover
