Dear Barry and Joe,Smithsonian magazine did an article (it's probably been 10 to 15 years ago) about a successful expedition to find the remains of Franklin's crew, ship, etc. Interesting, if macabre, article and worth (ahem) digging up for buffs of Artic expeditions gone bad.
The first version (and a lovely one) I ever heard of the tune was done by John Renbourne. I think he did it as "Lady Franklin's Lament" on the album "Maid in Bedlam". It's the version I still play. You'll find it in the DT under the name given above.
