Billy Joel wrote the song after returning to the East Coast from Los Angeles, where he had spent the previous three years.
Although FiO did not return from Los Angelas, he himself returned from ‘the 845’ which can mean a couple of things:
1. He is returning back to his New York City lifestyle which he faced everyday before introduced to “K.A” from ‘the 845’
2. He is returning back to the single life
Years later famous Queens rapper Nas, would write a song entitled “N.Y. State of Mind” in which he speaks mostly of how he himself views Queens everyday.
