Did Harpo Play the Harp?
There's a scene in Flying Deuces where Stan Laurel plays his bedsprings like a harp, and we here music much like that played by Harpo Marx in most films by The Marx Brothers. I've always wondered whether it was actually Harpo playing the harp on the soundtrack.
The scene is supposed to remind the audience of similar sequences in Marx Brothers pictures (cf. Duck Soup, for instance). Stan Laurel and Harpo Marx had a similar sense of humor, and it's certainly possible they were friends.
