“Nonesuch” a little instrumental featuring a bagpipe practice chanter. I had the vinyl back in the 60s but it took me decades to remember the name of the song (I had it confused with the name of the group) and lo and behold Qobuz had it. Golden Ring, “A gathering of friends for making music.” Folk Legacy, 1964.
Another tough one was “Minstrel from Gaul” by Richie Havens. Found his album “Stonehenge” (1970) on eBay, but never found it on streaming services.
