The lyrics describe a working-class "downtown man" attempting to woo a wealthy "uptown girl."
According to an interview with Howard Stern, Joel had originally titled the song "Uptown Girls" and it was conceived on an occasion when he was surrounded by Christie Brinkley, Whitney Houston and his then-girlfriend Elle Macpherson.
According to numerous interviews with Joel, the song was initially written about his relationship with Macpherson, but it ended up also becoming about his soon-to-be wife, Brinkley (both women being two of the most famous supermodels of the 1980s).
Joel has said that the song was inspired by the music of Frankie Valli and the Four Seasons.
The song was released on September 29, 1983, on his ninth studio album An Innocent Man (1983).
