Does anyone have any knowledge about Pat Foster?

The above is quite a comprehensive list. Wow!

I'll tell you about someone who you don't know, who in my opinion is one of the best
folksingers around today. His name is Chick Marston and he was a former fisherman from Gloucester, Mass. He plays a good guitar, lots of blues and ballads and is modest. He's married to a lady who sings very well named Ellen Ford, an alto who can belt out a tune with the best of them.

Barbara Barrow and Micheal Smith deserve to be mentioned. His song, "The Dutchman" is a classic.
