Lennon and Maisy Stella are from Ontario.... in Canada. They're young and incredible talented country musicians. Here they are, performing the June Carter-penned Johnny Cash classic.
Is there anything else I should be telling you about them? hmmmmmm....
Oh yeah! They're also on a little TV show called "Nashville" on ABC. This cover of the Lumineers "Ho Hey" made it to the Top 40 on the US Country charts. If you haven't watched the show, you should. It's one of the best shows on network television.
And yes, they let them perform it on the Opry without Connie Britton's dialog, too.
