Does anybody know of any songs from the East Anglia Fenlands? I'm particularly interested in songs that emphasise the flatness and (former/periodic/future?) wetness of the place, but to be honest any and all songs from the fens would be of interest to me.

Some google searching has let me to Mary Humphries' website, and I plan on getting her book of songs collected from Cambridgeshire by Vaughan-Williams. But I feel confident that there must be mudcatters who have songs that they've learned from this part of the world...
