Children are great "Authenticity Policemen"

When my elder daughter was a toddler we had a record of nursery rhymes sung by two singers by the names of John Lawrenson and Cynthia Glover (Do any other UK Catters remember them?). She loved that record and it was always on the player. In one of the songs, See Saw Margery Daw, they sang a second verse which you do not normally hear. My daughter once came up to us asking us for that verse with "Sing See Saw Margery Daw; wrong"
