Radriano, what I meant was I like what you thought it was "A good old fiddlers tune". I've only heard one of Landlocked sing it, that was at a party after the Swansea Maritme festival last July and there was a definite double "Dago" then.
Alan Fitzsimmons of The Keelers did write the tune that "we" sing, he used to be in a trio "Pinch of Salt" and they released a tape of Cicely Fox-Smith poems put to mucsic - Alan composing all tunes. It's from this tape that I picked it up.
About feeling uncomfortable singing the song it would of course depend on the company I'm in at the time. I've been in some circles, as no doubt has everyone here, where anything goes. Reckon it's a case of sizing up the situation before opening mouth.
You're a great bunch, glad I found you

Mike
