The first part of the documentary told the story of the Joel being in the band Attila with his best friend Jon Small, whom Joel eventually went to live with in a home occupied by Small, his wife Elizabeth Weber and their son. Weber reportedly said in the film that there was a “slow burn” between her and Joel.

Despite being a part of the new documentary, Weber noted that the two don't have a substantial relationship these days, saying, " [We’re] friendly but not close."

Weber, meanwhile, said that being "firmly planted in the public eye is the antithesis of what I wanted."

Billy Joel remains in good spirits despite his brain disorder diagnosis. The "Piano Man" shares his first public message with fans since his health battle announcement.
