Billy Joel's new HBO documentary, "And So It Goes," reveals two suicide attempts stemming from an affair with his best friend's wife. The affair caused the breakup of his band, Attila, and the end of his friendship. His first attempt resulted in a coma, while the second involved ingesting cleaning fluid. His ex-best friend saved his life. The experience led him to channel his emotions into music. Joel and the wife later married for several years. The documentary premiered at Tribeca Film Festival, though Joel couldn't attend due to a recent health diagnosis.
