A folk-song question I've wondered about

Okay, so we all know that " Charlie on the MTA" was written for Walter A. O'Brein's campaign for mayor of Boston. Some of us may even know that it was in 1949, that he lost badly, and even that his campaign was fined for disturbing the peace when he had cars drive around blaring that song out of loudspeakers.

But what I didn't know was that Walter A. O'Brien, progressive/liberal/Communist candidate for mayor, had a seven-plank platform, of which public transit support was only one plank -- and he had folksongs for all seven planks. Each one was, effectively, a filk, using the tune of a well-known folksong ("The Ship That Never Returned" is the source for "Charlie on the MTA".)

So. . .

Does anybody know what the other six songs were?

(no subject)

My wife has committed filk.
