Miles's version is the one I know, and since he wrote it, we might it assume it to be "correct"!

However, I do modify the second verse for the benefit of northern audiences who haven't heard of Basingstoke (or possibly the Isle of Wight!)

Twas in the year of '64, or was it '63?
When we set sail from Skelmersdale, bound for Amerikee.
The storms they were a rag-eye-ing and they did upset our plan
For it took us forty days, me boys, to reach the Isle of Man.
