Trying to find lyrics for 'Lundy Island Jim', which I remember being sung around folk-clubs of North Dorset in the late 1990s.

The chorus is something like:

I'm a lowly fisher lad
Just landed from the sea
Happy as a nightingale singing in a tree
As contented as the little fish
That in the channel swim
Come wet or dry, tis same to I
I'm Lundy Island Jim

But I can't remember any verses. Any lyrics (or pointers towards where it's from) would be very appreciated.
