This just in from Jeff Kutti:

[Jim Korkis may be referring to the film Roy O. Disney mentions in this quote from an interview of 1968 with Richard Hubler:

"As I have said before, Walt was a natural publicist, public relations type fellow. He was from the start… For example, real early in the game down here, you wanted to get your pictures into a good theater. We used to have a theater down here on Figueroa near Seventh street that was quite popular. The best pictures ran there then. So we happened to know the manager – got acquainted with him. Walt made a deal with him. We had a picture –Mickey Mouse. So we made a reel of Mickey coming out on the screen and leading the live orchestra down beneath him there. And then they took exception to him and they started quarrelling back and forth and then the live orchestra makes a gesture like they’re throwing things at Mickey. On the screen come all these things that drive Mickey off the screen. It was just a novel little introduction for him with his orchestra, and for that he booked our cartoon in the theater and he put it up on the marquee for one afternoon to give us time enough to get out there and photograph it. So with those pictures we could get it in the trade papers and so on, just to start making other exhibitors think they were worthy of booking."]
