When I began in the 70's I heard a modern version of this tune. Then I began to look for the 50's singers. Here is the original vid.
Jimmy & Johnny were an American country music duo comprised of Jimmy Lee Fautheree and Johnny "Country" Mathis. They scored several hits on the U.S. Country charts in the 1950s.
The duo's career began on the radio show Louisiana Hayride, where both were in demand as guests.
