Jim-

It's amazing how up to date old Harry was:

They say that ev'ry sailor has a wife in ev'ry port.
That's a lie, because he has got nothing of the sort.
If sailors have a wife in ev'ry port, well, take my tip,
That ev'ry sailor's wife has got a man on ev'ry ship.

I believe there is a contemporary song, composed decades later, that makes the same point.

Cheerily,
Charley Noble
