Billy Joel, whose music speaks a lot about him, is all set to open up about his complicated life in a new two-part HBO documentary 'Billy Joel: And So It Goes', according to People. The documentary, directed by Susan Lacy and Jessica Levin, is a rare, revelatory glimpse into the private world of one of rock music's most enduring acts -- and how he overcame substance abuse, mental health struggles and more to find peace and happiness with his wife, Alexis, and his three daughters.

Billy Joel to speak the truth in documentary

"I've resisted this kind of thing for so long. I'm sick of talking about myself," said Joel, adding, "Some of the stupid stuff I did, that's painful to talk about. But they asked me for some thematic guidance. I said, 'Just tell the truth.'"

"There was some stuff I found out about myself. There was some self-revelatory stuff," said Joel. He also thanked the director for connecting the dots of his life and giving him perspective.
