It's only because Harpo is so likeable as a person that I give three stars. Since Groucho never went in depth about the Marx Brothers in any of his books, I was hoping Harpo would provide more insight. Unfortunately, Harpo was very hung up about his social status, and his friendships with the Hollywood elite. Way too many pages are given to his relationship with Aleck Woolcott, and the endless stories of pinochle, croquet, pinchie winchie, etc.
The book does provide some interesting history, and what life was like during the vaudeville years. Again, this man probably has to be one of the nicest people who ever lived. He had a great life, and was a wonderful family man.
Overall, I recommend the book if you are interested in his personality. If you want to know how the Marx Brothers got along or any other in-depth detail on them, you will be disappointed.
