Interesting...the Joy Buzzards was also the name of a recent (now defunct, I believe) band that included Robert Armstrong, the comic artist.

From their CDBaby web site selling their CD:
"Our material is a mix of jugband,blues,20s jazz, novelty,hillbilly,Hawaiian and out-there, with each song having its own distinct heritage and flavor."

Hitler and Disney? Too good to be true. HAS to be a forgery. Paging Malcolm Gladwell...

Everything Dust to Digital does is terrific; I particularly like the Goodbye to Babylon gospel set.

I think it is a very old legend; the Scottish singer Andy M Stewart who sang with the 1980s band Silly Wizard wrote a song called "The Orphan's Wedding" that was supposedly based upon the very same "true" story.
