Yes, we did record it from Walter Pardon and it is deposited at the National Sound Archive at The British Library with the rest of our collection (don't know if it's accessible on line).
I don't think it has been released commercially, I can't recall it being on any of Mike Yates' albums of Walter.
Personally, it's a song I'm not entirely comfortable with and would think twice before passing it on (I think this is the only song in our collection I feel this way about) - otherwise you would be very welcome to it.
