BackStage Pass VIP, a new book by Debra Sharon Davis, "depicts the human side of celebrity music icons." Among other claims, the controversial book paints Mick Jagger as a right-wing conservative and claims that John Lennon had an eating disorder.

According to Davis:

Lennon was confused about his obsession with food. Lennon was surrounded by talented musicians, but many had drinking and drug problems – so it was hard for them to see Lennon's purging behavior as extraordinary. One must also realize that at that time the public and the media were unaware of bulimia as an addiction and health risk – which made it all the more frightening for John Lennon. He literally had no point-of-reference on what he was experiencing.

The book relies on a candid interview with friend and contemporary, Harry Nilsson, who supposedly knew about Lennon's struggle with food.
