Tarpaulin Jacket is one of the most-parodied songs in existence. It's been used by sailors, skiers, spelunkers, soldiers, paratroopers...anyone who wants to stress the dangers in his/her avocation or profession. My favorite is The Dying Airman (in the DT), but there are lots.

The tune I've always heard (well, it seems like always) was a lot closer to Botany Bay than to Rosin the Beau.
