Besides the invaluable footage of Nick La Rocca and the '37 ODJB, and the revived acoustic recording gear at Victor (they kept it around all those years??) there are many other fascinating details in this film that should attract the attention of observant Forumites:
The names "Original Wolverines" and "Bix Beiderbecke" among the "swing" notables listed in the sign on the wall of the record store; also (0:18): "Frank Trumbauer's Saxophone Studies" among the sheet music in the store.
Fifteen precious seconds of actual live sound footage of Chick Webb and his Orchestra at the Savoy Ballroom, including (later in the piece) a closeup of Chick at the drums. It's the only film of this band in existence that I'm aware of.
A very authentic-looking Western Union telegram, possibly from the scrapbook of Nick La Rocca:

"Playing Nightly - Hear Gus Keefe and his Dreamland Syncopators at Lakeside Pavilion" on a spare tire cover. Were they a real band?
Actual live sound footage of Stuff Smith and his Onyx Club Boys, at the Onyx on 52nd street, with Jonah Jones on trumpet. Probably as rare as the Webb footage.
The "Jazz Literature" Montage:
NICE dust jacket on that 1936 first edition of "Swing That Music" by Louis Armstrong.
Magazine article: "Debunking Swing" by Sam Rowland: "How the public became infected with swing fever, which was at first confined to musicians." Can we read this?

(This was the concert where Artie Shaw made his big breakthrough, according to Lost Chords.)
Fantastic "hot jazz" art by Miguel Covarrubias
A glimpse of the cover and the N. O. R. K. section of the 1936 first edition of Delaunay's Hot Discography.
Those STACKS and SHELVES of all-pre-1938 records!!
Finally, did the "March of Time" announcer lend his voice to the "News on the March" sequence that begins Citizen Kane? If not, it was a pitch-perfect imitation.
