Asked if he had any advice for Slash and Axl Rose - who have not spoken for years - McKagan tells Northjersey.com: "I just wrote about something that I understand about myself. Over time I've gotten rid of a lot of resentment I didn't know I was even carrying around. I don't try to impart anything in the book, though, but if I can write about things without being preachy and people get something out of it, that's great."
