I also found this bio info on his MySpace, quite possible HE wrote "The People's Folksinger"

Bob A. Feldman started writing and singing protest folk songs in the Guthrie-Ochs tradition during the politically and culturally turbulent 1960s. Some of his protest folk songs were written in the dormitories of Columbia University or inside some Upper West Side apartment buildings. After being suspended from Columbia University for political reasons following the April-May 1968 Columbia University Anti-War Student Revolt, Feldman continued to write protest folk songs during the following four decades on a non-commercial basis. He also has written a lot of love songs and occasionally sings at folk music club song swap sessions. If you're an anti-war music fan, like topical folk songs, and believe that folk music should be used mainly as a tool for radical democratic social change (and not used just to entertain people or just for commercial purposes), then you'll probably be interested in listening to Bob A. Feldman sing some of the 200 protest folk songs and folk love songs he's written since the 1960s.
