Organ Grinder

A specific type of Street Performer, the Organ Grinder is a Street Musician who would make a living turning the crank on a self-performing organ (sometimes mistakenly called a hurdy-gurdy), usually with a trained monkey on a leash dancing around--alternatively, the monkey is the one turning the organ, and the human is just there to hold the leash.

More or less a Dead Horse Trope these days, but expect them to pop up in stories set in the 19th and early 20th century. (They've actually been banned in quite a few cities, both because of complaints about the excessive noise they make and because of copyright violations by some of the musicians.)

Film
"Crow: WOULD SOMEONE PLEASE SHUT UP THE ORGAN GRINDER?"
 * In Batman Returns the Penguin's circus gang had an evil organ grinder amongst their ranks. (actually he was apparently very high in command) His organ contained a hand cranked machine gun. (In the Super Nintendo game based on the movie, he fires bullets at Batman and then just tries to hit Batman with the organ when he gets too close.)
 * If you think about it, it was kind of a stretch, since organ grinders are usually thought of as stand-alone street entertainers rather than members of circus troupes.
 * Tia Dalma uses an organ grinder as a signal to some of the Black Pearl pirates in Pirates of the Caribbean: At World's End.
 * One can be seen on the street in one scene of the Mexican film Santa Claus. He's easy to miss, unless you're watching the Mystery Science Theater 3000 version:
