Billy Joel bared it all in Billy Joel: And So It Goes. The two-part HBO documentary - released on July 18 and July 25 - offered an inside look into the Piano Man's life, exploring "the love, loss, and personal struggles that fuel his songwriting," according to the film's official description. "I'm not finished. ... I'm still looking. I'm still searching," Joel, 76, told viewers in the second part of the film. "I may not ever figure it all out. But I'm trying." After making the film, the singer was diagnosed with normal pressure hydrocephalus in May.
