I recognized the name Ethel Raim from the 1960s and thought (correctly) that she was in the Pennywhistlers and that she was involved in Sing Out magazine. I didn't know that Ethel Raim was still active and about (Gerry M writes of Ethel teaching a workshop in 2021). But I think she was fairly prominent in the folk/traditional scene in the US back in the 60s.
