I remember a play/event called The Shipbuilder, possibly at Whitby Folk Festival a while back(15ish years?). Outside on a bit of a beach somewhere, anyway. Taffy Thomas directing, I think, John Kirkpatrick and various folks on the music. Don't know who wrote the songs, or what they were like: but a certain amount of shipbuilding was involved, as the name would suggest. Ring any bells, anyone?
