How's the Don Redman flick? (I assume it's a short subject.) He's one of my American Songbook heroes for having written "Gee Baby, Ain't I Good to You?".
I've watched so many of those old Vitaphone shorts (which are all pretty wonderful in their way) lately that I don't even remember which one was Redman.
The Vitaphone shorts I'm in the middle of right now are actually pretty painful -- compilations of scenes from silent serials, with the addition of really unfunny narration (the clips are great, though - I'd almost be tempted to watch then without the sound)
