Nice guy Franklin, whose amiable talkfests provide TV time for faded jazzmen, green young comics, and authors of remaindered books, talks about how he does it. With a smile and the magical word ""yes."" Among the folk he's said yes to: Barbra Streisand, Flip Wilson, Don Rickles, and his beloved ""three B's""--Mrs. Babe Ruth, Shirley Temple Black, and Bing Crosby. Affirmation's the thing here and Franklin's delight is making others shine: ""To me everybody's a star and I tell 'em that."" No ""hard"" questions, no confrontations, no baiting the guests. His famed open-door policy--his studio's always packed With strays, discards, and aspiring everythings--originated, he says, with his father, who often brought home indigent strangers for dinner and a bath. Franklin's nostalgia is of a very tangible kind--60,000 old records and a private archive of 7,500 old movies cherished and made available to guests and friends. On the tube or off, it's always accentuate the positive, let a smile be your umbrella, and pennies from heaven for Franklin whose soft-core take on life is a marshmallow-lover's delight.
