I fine article it is! I'd suggest the other way 'round... that Maitland may have gotten his chorus from Tayluer (who was born in Maitland!).

My reasoning is that Matiland's version, which he purportedly overheard being sung by a sailor in the fo'c's'le, is a forebitter... no chorus required. Tayluer specifically identifies his version as a hauling chantey.
