It is somewhat more than just changing names, but it is hardly original. I tried to keep as close to the classic story as possible based on a couple of versions. As I recall, some lines are exactly the same, but most had to be adjusted to fit under the sea or in with the rest that I wrote. Some changes, such as the pun "wise and wry," just sounded better to me than "great and high." Here is one of the versions for comparison.
