George Ezra stopped by The Late Late Show with James Corden last week to perform his single, "Budapest." Now, in a new video, the two actually take a crack at harmonizing together -- at least that what James Corden thought.

Filmed in the show's green room, Ezra, his guitarist and Corden -- with shakers in hand -- start performing "Blame It on Me," from the artist's debut full-length album, Wanted on Voyage. While it looked like they were going to just jam together on the tune, Ezra made sure to set Corden straight when he started to join in on the song.

It's not that the late night host couldn't sing -- he was one of the stars of the Disney musical, Into the Woods, but Ezra wanted this to be a solo effort instead of a duet. While back and forth banter continued, the two finally perform the track together. And it sounds spot on; maybe Corden should join Ezra to perform it live one day. You can see the jam session above and catch Ezra's performance of "Budapest" on The Late Late Show below.

Ezra is playing Philadelphia's Trocadero Theatre tonight (April 21) and Webster Hall in New York City tomorrow (April 22). He will then spend May and the rest of the summer touring around Europe.
