Peggy Cass was a tad (several tads, maybe) larger in size.
I don’t know why I’m so into this , but you’re right, Peggy
Cass was bigger and more matronly looking. So it’s probably
Polly Bergen, and BOTH of them were on the show for years and years; Dick Clark doesn’t make the cast list for ANY year, so it remains a mystery just who that guy 2nd from left is. But I am on it !
lOOKED AGAIN and it’s definitely Johnny Carson 2nd from left. Still not quite sure it’s Polly Bergen, though.
