re: Scarbourough Fair.

I once sent Peter Yarrow the lyrics to this poem I found, called "The Lover's Task", Sugesting that he and the trio (Peter Paul and Mary) should record it. His reply was: "Riddle songs are out." A few years later these two kids who called themselves Tom and Jerry, changed their name to Simon and Garfunkle and recorded the song as Scarborough Fair. And yes PS takes credit for it.

At least P,P,&M would publish as "adapted and arranged by"
