Thanks to all who helped with "I don't know who you are sir etc"..Mudcat is very impressive.
Here we go again. Many years ago, A London singer named John Foreman sand (again) an old Music Hall song called "Marri-i-ed to a merm-i-ed at the bottom of the deep blue sea"...or at least, that was the last line of the chorus. The beginning line was "Twas in the mid Atlantic, mid an equinoxial gale, a younf fellow fell overboard, beneath the sharks and whales" etc.
Answers please if you can....and whatever happened to John Foreman?
