“I don’t think it’s a secret that his drinking got pretty bad,” Brinkley said in Part 2 of the musician’s new HBO documentary, Billy Joel: And So It Goes. She said that the singer “couldn’t really remember what he did when he was drinking, and so he didn’t really know how he could hurt people.”

Weber and Joel first met in the late 1960s, as he was best friends and bandmates with Jon Small, Weber’s then-husband. In 1969, for the sake of musical convenience and financial benefit, Joel moved in with the couple and their young son, Sean.
