Hmm! Lloyd and MacColl's list 1956, practically the same as Hodgart's, 1950. A case of great minds think alike, or perhaps just a case of cribbing?

Froggy certainly has a long pedigree, Dick, and comes in several distinct forms due to being rewritten for different audiences, but by the time Child was aware of it it had very much become mostly a nursery song. And of course animals talking and behaving like humans, whatever next! They'll be saying ballads have a cartoon-like quality next!
