For what it's worth department: My business partner in Folk-Legacy Records, namely Lee Haggerty, had an uncle (an admiral in the US Navy) who sang (?) an American version of this that I have never seen printed. He knew it as "Cruising 'Round Norfolk." Unfortunately, he could remember only a small part of it and, like my partner, he couldn't carry a tune in a bucket. I'm curious if any of you experts out there have run across the Norfolk version anywhere.
