Neil Patrick Harris, James Corden Sing 'Hamilton' in Broadway Riff-Off

'The Late Late Show'

The two Tony winners and hosts also took on 'Guys & Dolls,' 'Gypsy,' 'Company' and 'Les Miserables.'

There's only room for one man on TV who can star in a show and crow about winning a Tony Award.

At least that's what Neil Patrick Harris thinks, which is why the A Series of Unfortunate Events star interrupted James Corden's The Late Late Show monologue on Monday night to challenge the host to a Broadway riff-off to prove ultimate Great White Way supremacy.

"Your silly jokes can wait, Corden, we have a score to settle and it's about...Broadway," Harris said with a serious look. "I see you going around, hosting the Tonys, acting like you're the only TV star who can sing Broadway show tunes.... Some of us, dude, have actually won a Tony." 

When Corden reminded his rival that he, too, had won a Tony, Harris scoffed, "Yeah, for a non-singing role. Burn!" At which point it was on. Joined by the a cappella group The Filharmonic, the two squared off for battle, with Corden throwing out the Guys & Dolls classic "Sit Down, You're Rockin' the Boat" and Gypsy's "Everything's Coming Up Roses," plus hits from Company, Les Miserables and Hamilton.
