And in truth, of course, I’m not just 60 — I’m twelve, I’m 23, I’m 37, I’m 42, I’m 18. I’m every age I’ve ever been. Depending on what day of the week it is and what the situation calls for at the moment.

[Und in Wahrheit bin ich natürlich nicht nur 60 – ich bin zwölf, ich bin 23, ich bin 37, ich bin 42, ich bin 18. Ich habe jedes Alter, das ich je gehabt habe. Je nachdem, welcher Wochentag ist und was die Situation gerade erfordert.]

William Martin "Billy" Joel (b. 1949) American singer, songwriter, pianist
“Ohne die Nazis hätte es Billy Joel nie gegeben,” Die Welt (2009-05-10)

This interview is published in German, but in it Joel comments he only knows a bit of the language (his father was a Jewish refugee from Germany before WW2), so it was likely conducted in English. The German version is from the article. The English version is from Wikiquote (source unknown), which titles the article "Without the Nazis, there wouldn't have been Billy Joel."
