I was sure I had an old Bellafonte LP with this on it but a search on hands and knees through a thick satack uncivered four LP's by Harry but none with this song.

My recollection starts:

"If you want to be happy and lead a king's life,
Never make a pretty women your wife ..."

and ended:

"So from a logical point of view,
Always marry a women uglier than you!"

Could it have been the Mighty Sparrow? But Country or Calypso, the message of male insecurity rings pretty clear!
