Who's Benjamin Williams, Garg? I closed the other thread and crosslinked to this one, because this one had already answered half the question. Didn't make sense to split the answer into two threads.

As Bee-Dubya-Ell said above, information on the book is available from this site (click) - it's for sale for ten bucks from the Parallel Press of the University of Wisconsin. The "Them Poems" I posted above are identified on the Julesarts website as having been written by Mason Williams - but were they?

The only "Them Poems" I've heard on recordings are the three done by the Kingston Trio on Back in Town:

Lunch Toters

Stamp Lickers

Them Hors d'oeuvres

Also see The Mason William Webpage for a list of more "Them Poems" - but I can't tell if it's complete.
