Ozzy Osbourne and his son, Jack, have been filming a new show for the History Channel, in which the Black Sabbath frontman travels to unique historical sites, since last fall. So far, they’ve visited the Alamo – where Osbourne apologized for urinating on the monument three decades earlier – Stonehenge, Roswell, New Mexico, Havana, Cuba and Mount Rushmore, among other places. It’s an experience for which the singer is grateful.

“After The Osbournes TV show, my son chose to go behind the camera and he’s got his own company,” Osbourne tells Rolling Stone. “He said, ‘Would you be interested in doing this show?’ And I went, ‘Oh, great, fine.’ I just got back from Cuba last week, which, incidentally, if you get any chance to go over there you should go, mate. It’s fucking great.”

Havana left a strong impression on the singer, who lauds how cheap things are, how easy it is to navigate and its abundance of “fucking mind-blowing” architecture and classic cars. He also enjoyed visiting a war memorial built after the Cuban Missile Crisis. “They got parts of a fucking U-2 plane lying around in this military thing in a park and you can just go and touch it,” Osbourne says. “And I’m going, ‘Fucking hell. If that was in England or America, they’d have a fucking screen that you couldn’t touch this stuff.’ Then somebody pointed out to me that under the Castro regime, it’s everybody’s property. It’s not a government thing … but it’s kind of weird.”
