This is an interesting question. I thought of the "The Ship that Never Returned" which is the basis for "The Wreck Old 97" which is the basis of "The Municipal Train Protest Song" (MTA), which is the basis of "Super Skier." Not quite as many as Rosin the Beau.
With regard to Rosin the Beau, the Limeliters did a parody called "Acres of Limeliters." Randy Sparks and the New Christy Minstrels did a song entitled "Denver" to that tune. I believe it was also the basis for a campaign song,"The Hero of Tippecanoe," for William Henry Harrison. I'm sure there are others, but those are ones that come to mind.
