"The Tonight Show" is back in the city for the first time in more than four decades.
Jimmy Fallon debuted at midnight Tuesday with a lot of star power, including appearances by Robert De Niro, Tina Fey and Joan Rivers.
The show is taping in the same studio where Johnny Carson used to tape the Tonight Show, before the production was moved to the West Coast.
While the show is moving across the country, Fallon is just moving down the hall. He also hosted "Late Night" for the past four years inside NBC Studios at Rockefeller Plaza.
NY1 caught up with lucky audience members who were there for the first taping, and they're already calling him the new king of late night.
"He seemed really calm," said one person. "He can be kind of an emotional guy because he has such a big heart, but it was a really fun show."
"I've been following his career since SNL. I've watched most late night shows," said another. "So excited for Jimmy to take over 'The Tonight Show.'"
"Honestly, my dad was a really big fan of Jay Leno. To be honest, we're from Canada, and coming in this weekend, he was like, 'You're wasting your time. Jay Leno's so much better. Jimmy is going to fail like Conan,'" said a third. "And I can safely say that after this episode here, my dad's very wrong."
U2 and Will Smith also appeared as guests.
