In his new HBO documentary, Billy Joel addresses his feud with Elton John and talks about his career; however, it quietly ignores one major aspect of the musician's life.

There was once some “bad blood” between Elton John and Billy Joel.

John’s full quote wasn’t exactly subtle. He blamed Joel’s alcoholism for tour cancellations, accused him of “coasting,” and described Joel’s rehab stints as “light,” quipping that when he went to rehab, he had to clean the floors, while Joel had TVs.

As insiders explained to Page Six, the "Piano Man" crafted his buttoned-up stage style with help from his first wife and former manager, Elizabeth Weber. Weber not only helped build his career, but also helped shape his image, down to the orange blazer seen on the cover of "It’s Still Rock and Roll to Me."
