To Dave in Seattle: I've known Len since very early in our respective careers in folk music. I still speak with him now and then. I learned both To Be a Man and Keep on Keeping On directly from him. I suppose one can never know for certain what goes on out of sight, but to the best of my knowledge Len wrote both songs himself - and everything else he recorded. He sometimes borrowed melodies, and I've heard him say Green Green Rocky Road was based on a children's game, but for ten years I opened all my shows with Keep On Keeping On - I always introduced it as a Len composition and no one ever corrected me.
