I can name that tune in four notes. Literally. Guess what? RAGTIME the
Musical - the main theme - "They Called It Ragtime.". I pretty much
expected that as you saw, so no surprise. Not Joplin by any stretch,
and the publication only missed his death by 81 years. The composer of
the music is actually Stephen Flaherty, and he comes closer to ragtime
than Randy Newman did in the film adaptation done in 1981.
You can find the soundtrack, well, almost anywhere. Amazon link is:
If you want the music, it can be found at the usual suspect music
stores and internet outlets, including Amazon at:
Hope that is helpful. Now if we can just get this "unknown" fragment
either title or off the internet altogether, and at the very least
disassociated with Joplin, that would provide clarity.
