I remember growing up only knowing Alberghetti from those Good Seasons salad dressing commercials - and finding out later that the "salad dressing lady" was the star of Carnival. :-)
(That happened with a lot of TV personalities who did Broadway - me knowing them from TV first. Beth Howland (Alice), Robert Mandan (Soap), Bonnie Franklin (One Day At A Time) etc. It was always fun to then see them in the cast lists of Broadway musicals.
