So, the Kingston Trio's MTA rang no bells, huh. It is in fact a folk song which is a send-up of another folk song about a train that was even memorialized with a plaquard sign at the spot where it wrecked.
The MTA is about Massachusetts Transit Authority using the tune originally from "The Wreck of the Old 97", about an actual mail train of Southern Rail. The tune was borrowed by numerous other songs besides--it's so catchy y'all best learn how it goes, folksongists.
That's because it borrowed from "The Ship That Never Returned" and boy howdy there were copyright lawsuits to be found.

Original copyright was in the 1800's so it's all public domain now, folks. The Kingston Trio used the tune for "MTA" with impunity, kind of like how it was with the Andrews Sisters and "Rum and Coca Cola".
The guy who witnessed the 97 wreck wrote the lyrics, not the music, and it was Morey Amsterdam that wrote the lyrics, not the music, for "Rum and Coca Cola"; the original, done by Abe Lymon, was court ordered to be destroyed (master, too), but that didn't stop the Andrews Sisters via a different label.
