Paul, wasn't "Parchment Farm" maybe the last "new" Kingston Trio song to make radio airplay? I remember it being February/March 1965, as that March, my Lions Club Midget Hockey Team had just won the Midget Division Championship, and "Parchment Farm" was playing on WBBF Radio 950 AM. I don't recall hearing any other new KT songs on that station after early 1965.
