Thanks, Barbara, I have The Complete Folkways Recordings 1958, Smithsonian CD SF 40066, which does not have this song on it, unfortunately. I also have the CD _called_ Out On The Rolling Sea (tribute to JS) which at the very end, _after_ the last track has Joseph Spence just saying "On the rolling sea" a coupla times and laughing in that way he does.
I'll have to try to find Spence and the Pinder family together on CD somewhere. I live in a cultural desert called Western Australia, which has no shops (well, you can buy food), so I rely on mail order CD stores in the UK and States.
At least I have a coupla titles from this thread.
