I guess my favourite version has to be by Pete Seeger, with nods to The Byrds/Roger McGuinn.
Interesting to have a trip through Spotify, quickly skipping past the version by Cher. Judy Collins does a good job and the six- or twelve-string question is answered by Bob Davenport who does an acapella version - with a tune much closer to the nursery rhyme of my childhood.

Way back, probably my first venture into Mudcat, I answered a query about Len Partridge from Edinburgh. The late, great Hamish Henderson once introduced Len to Pete with the words, "This is Len, he can play "The Bells of Rhymney" better than you."!
