For quite a while I have performed a "pseudo-folksong," that was certainly not traditional by any means, but what originally done in a very folk style in 1957 by.....................Dean Martin.

"Memories Ae Made of This" does sound very folky and was recorded with just two guitars and upright bass. If I am not mistaken, Terry Gilkyson of the folk group The Tarriers was one of the guitarists. He was in fact one of the song's writers.

So I guess this does fit the subject of this thread to a T.

Dean Martin could handle a folk song quite well and the same with many country songs.
