Billy Joel is slowly filling in his 2020 itinerary -- which means, a return to the ballparks. New shows on the books include summertime stops at Boston's Fenway Park, Detroit's Comerica Park, and Cincinnati's Great American Ball Park. Billy's also playing a baseball stadium south of the border, when he hits Mexico City's 65,000-seater Foro Sol stadium.

Although born in the Bronx, Billy told us that -- like many New Yorkers -- as a kid, he actually followed the Brooklyn Dodgers: "I started out as a Brooklyn Dodger fan. And the Dodgers moved, I think it was '57 or '58, and really cheesed me off. So I didn't just switch teams, I switched leagues, and I jumped to the Yankees."

Billy Joel explained that although there's plenty of blood, sweat, and tears in his songs -- his music isn't something he listens to when kicking back: "I don't sit at home and listen to my music. I write the music, I write the words, then I arrange it, then I rehearse it, then I record it, I play it on the piano, then I sing, then I mix it, then I master it, then we video it, then we, uh, rehearse for the tour, then we play it on tour thousands of times -- so when I go home, it shouldn't be surprising that I don't go home and play my own recordings. But if it comes on the radio, then I turn the volume way up, 'cause, y'know, 'Hey, cool, somebody else played this!'"
