Thanks for the link, MMario!

Interesting... Though the aspect of the Dram Tree Legend that interests me most (aside from the fact that it is local to where I am, at the southern end of the Chesapeake Bay), is that requirement isn't to pay the spirit of the tree, but to pay respects to other sailors (giving and sharing in rum), and that the tree is more like an arbitor of social justice, weeding out the greedy and selfish.

Though I suppose that the same spirit is at the root of Halfway Rock... It certainly has given me something more to think about... Is there a midi or NWC file for the tune, do you know? I don't have ABC...
