WATCH: American Authors on Jay Leno Performing “Best Day Of My Life”

American Authors (Formerly The Blue Pages) are making their way. They just released an EP and they have a song on two commercials (Lowes, and something on the History Channel).

Now they’ve made their television debut on Jay Leno’s late night program. They played their single “Best Day Of My Life” Oh and Zac Barnett got to shake Simon Cowell’s hand.

Watch the performance below.
