\n\tIn the official trailer for Billy Joel<\/a>: And So It Goes<\/em>, the musician considers a reality in which \u201cUptown Girl\u201d was a Mozart piece. It\u2019s not entirely farfetched. His history as a musician started with listening to classical music. Besides, the singer and songwriter has learned not to count out the impossible. \u201cSometimes it\u2019s alien to me \u2014 this guy, Billy Joel. I don\u2019t know who that is, or what that is,\u201d he says in the clip from the two-part HBO<\/a> documentary<\/a>. \u201cI\u2019m reminded of it when I go walk on the street. Oh, right, I\u2019m that guy.\u201d<\/p>\n \n\tJoel doesn\u2019t have an explanation for how his first band, the Hassles, were ever successful (\u201cI don\u2019t know one person that liked what we were doing\u201d) or how he ended up dating the supermodel Christie Brinkley (\u201cMe? I\u2019m from Hicksville\u201d). Still, he thinks he has the secret to the music mostly figured out. \u201cIf there was a skeleton key to unlocking what\u2019s behind the songs, it\u2019s my relationship with others,\u201d he said.<\/p>\n
