Query: The Button-Down Autobiography of Bob Newhart

I have enjoyed Bob Newhart's unique, low-key style for years on t.v., on recordings and in the movies. This is a book that tells about some of Newhart's off-screen life--the tough, early years, the somewhat unusual courtship of Bob's wife, his passion for golf, and his enjoyment of family and friends. He intersperses stories of his life with comic routines he developed over the years. He has a delightful sense of the absurd and has always done clean comedy which is suitable for any age. His longstanding marriage of well over 40 years attests to his devotion to his wife and children. There are some surprises, such as the fact that his best friend is Don Rickles. (Who knew?) He describes Rickles in his private life as being much different from the caustic, sharp-tongued comedian that audiences see. People who are over a certain age and have seen Newhart perform will probably enjoy this book much more than those in their 20's and 30's.
