What a star you are. I have now acquired an old vinyl titled 'Sound Barrier' on which Alan sings Wroxam Broads. To me a superbly constructed song. Wroxham Broad is indeed an area of wetland to the west of Gt Yarmouth, a superb area of natural beauty and very popular with holiday makers. Go there if you can. Alan Smethurst ( the singing postman ) deserves more recognition than he has at present. Some say his songs are twee but have a listen and make your own judgement. I will search your other links to see what they have in store.
