Hi, Mary -
"Bluenose" is registered at Songfile.com, so all you do is go to songfile and pay for a license. It's not horribly expensive.

I'm still waiting for a reply from John Roberts, and I'm guessing he will say the same thing as Dave Webber and Ani Fentiman - that Dick Swain informally gave them verbal permission before he died, and that there's no evidence that Dick registered a copyright on the melody.

"Shipyard Apprentice" is also registered at songfile.com, so I'd suggest getting a license there.
