Mervyn (Vincent) and I were friends for years, but I don't remember him singing the Cadgwith Anthem (except in the chorus). He was generally banned from the Ringers in St Issey (except over May Day) where the extra verses emerged. My vague recollection is that I got the song from Vic Legge of Bodmin, but I may be wrong.

Anybody remember the early days when Martin Winsor and myself worked behind the bar and all those wonderful songs just went on all night? Port and Brandy in the morning to recover!

Sorry this gets nowhere nearer the origins but it's nice to reminisce!
