Francis Redfern was the author of History and Antiquities of the Town and Neighbourhood of Uttoxeter (1886) and although he refers to souling, he only gives the first verse of the song. The words are very similar to souling songs in Cheshire, eg in Alderley and Barthomley, if I remember correctly. I think it was also published in Ormerod's History of Cheshire.
