Jimmy Fallon gave his friend Billy Joel and his documentary a shoutout on 'The Tonight Show Starring Jimmy Fallon' on Thursday night.

Billy Joel has opened up about his father and his family’s holocaust history in the second part of his HBO documentary, titled And So It Goes.

"I’m tipping over sacred cows all my life. I like to do that," he said as he sat by his piano. "There is a code within the music itself that has nothing to do with the words, that takes you to this place, if it’s done right." This then led the "Piano Man" singer to talk about his love for classical music.
