In celebration of Billy Joel's 100th career performance last week at New York's Madison Square Garden, the "Piano Man" sat down with and spoke candidly about many subjects -- including his 25 years since last writing rock songs to the troubled presidency of Donald Trump.

Billy was asked about what made him walk away from writing and recording new music following 1993's chart-topping multi-platinum River Of Dreams album. He explained, "The last album I did was as good and maybe better than a lot of other albums that I had made, but it got no airplay. (The title track) was a hit, but nothing else on the album did anything. The thing was, I put a lot of work into River Of Dreams and it was as if the business had left me behind because there are substantial songs on that album that never went anywhere. So I said, 'What’s the point of putting myself through writing and recording if it doesn’t mean what it’s supposed to mean out there in the world?' You work so hard on your stuff and you want people to hear it. If it doesn’t get exposure -- the nature of the album format is for that album to get disseminated and River Of Dreams didn’t. . . . I just had higher expectations for it. Then the record company came in and said, 'Okay, what’s your next album going to be?' And I went, 'No, that’s it.'"

Billy, who plays a monthly gig at MSG and usually plays another out of town show, was asked about headlining a Broadway residency similar to Bruce Springsteen's: "I don’t want to work five nights a week like he does. And because of the kind of show he’s doing he can’t go off script. We play the Garden once a month and change our show all the time. If I feel like singing (Procol Harum's) 'A Whiter Shade Of Pale,' I do it. If someone is in town and wants to come play with us, they can."

He touched upon his decision to wear a yellow 'Star of David' during his August 21st show at the Garden as a message to Donald Trump in the wake of the White Nationalist protest in Charlottesville, Virginia. Billy said, "It wasn’t about politics. To me, what happened in Charlottesville was like war. When Trump said there were good people on both sides -- there are no good Nazis. There are no good Ku Klux Klan people. Don’t equivocate that sh**. So when those guys see punks walking around with swastikas, how do they keep from taking a baseball bat and bashing those crypto-Nazis over the head? Those creeps are going to march through the streets of my country? Uh-uh. I was personally offended. That’s why I wore that yellow star. I had to do something, and I didn’t think speaking about it was going to be as impactful."

This week, Billy spoke about his decision to wear the yellow 'Star of David' -- which Jews in Eastern Europe were forced to wear prior to and post "the night of broken glass," marking was the start of the Holocaust which exterminated over six million Jews at the hands of the Adolf Hitler and the Nazis. Billy explained to CBS News how he's shied away from political issues in the past, but Trump's actions forced him to show exactly where he stood: "No, I don't think it's right for me to get up on a soapbox, because that's not why people are there. I had to do something that night. The president said, 'there's some good people on. . . y'know, that did. . .' No. Nazi's aren't good people. It really enraged me, actually. My old man, his family got wiped out. They were slaughtered in Auschwitz -- him and his parents were able to get out. But then, he was in the U.S. Army during the war and fought with (General) Patton and was shot at by Nazis. My family suffered and I actually think I have a right to do that."
