re: Johnny Carson, by Henry Bushkin

Did you find the book credible? I've read about one of the stories he told, about Johnny taking a gun to go break into his wife's apartment because he thought she was cheating on him w/ Frank Gifford. The ex-wife said it was all bullshite, and that Johnny would never carry a gun. Kathie Lee Gifford also said she asked Frank about it and that particular affair was not true.
