It’s not often that you’ll see a musician go on The Tonight Show for what essentially amounts to show-and-tell, but that’s just what Neil Young and Jack White did last night as they brought the Third Man Records Voice-O-Graph recording booth to Jimmy Fallon’s stage for a demonstration.

The pair are out promoting Young’s new record, A Letter Home, which White released on Third Man earlier this year. Young recorded the album on a similar device housed at the Third Man Records store in Nashville, and, after a quick interview where Young gave his take on the Tonight Show host’s uncanny impersonation of vintage Neil, the singer-songwriter headed into the booth to cut a recording of Willie Nelson’s “Crazy.”

The show closed with Young, White, Fallon, and comedian Louis CK listening to the playback of Young’s recording. It may be the first time a musician has gone on The Tonight Show to play their own record, but the process is an interesting one to watch. You can check it out in the video below.
