James Corden has Broadway in his blood, and ET found him having the time of his life during the final rehearsals for the Tony Awards.

"There are going to be performances and things you will never see anywhere else," Corden promised ET.

EXCLUSIVE: Why James Corden Is the Right Man to Host the Tony Awards

The Late Late Show host has come a long way since 2012. Four years ago, he was accepting the Tony Award for Best Actor in a Play for his turn in One Man, Two Guvnors, and now he's running the show.

One of the staples from his talk show is the hugely popular "Carpool Karaoke," in which he drives around with celebrities singing along to their own songs on the radio, and there's a chance he will bring a version of the segment to the awards show.

"I don't know if I will, but I am going to try to have a bit of a sing-a-long in their commercial breaks," Corden said.

With stars like Oprah Winfrey and Barbra Streisand in the audience, that could potentially be one epic jam session, but Corden isn't holding his breath.

"They're not going to sing, and it might be a disaster," Corden warned. "People could be looking at me like, 'What are you doing?'"

Hamilton, the rap musical about America's Founding Fathers, is up for 16 nominations and might assist Corden with his hosting duties.

"I am not going to give that away, but you can't ignore it," Corden said about a possible Hamilton-inspired opening. "The show is a phenomenon!"

The Tony Awards air Sunday at 8 p.m. ET/PT, 7 p.m. CT on CBS.
