Ralph Harden founded in the late 1950s a vocal group called The Newports (after the city where he lived, Newport News, Virginia.).
In addition to being her leader, he was the composer of her songs such as "O-Om Diddy Waddy Wah / Times Hurries By / There She Goes Again and Walk With Me".
The group consisted of In the picture is (from left): Bob Fowler, Ron Fowler, Frank Moore, Ralph Harden and in front is Roy Hare.
There is only one song of theirs on Youtube in a pop style so I wonder if in any of the other songs mentioned above they will sing in a doo wop style.
Listen to them...
