Thanks all, I guess my memory's not that bad after all. I did have MacColl & Seeger's "Travellers' Songs From England & Scotland" And Sam Henry's "Songs of the People" but didn't think to check either of those as sources, DUH!. Thanks for leading me back to those. I ended up singing it Tuesday night at the Gloucester (Mass, US) session knowing that I did already have it.

Thanks to everybody
Barry
