At Jack Antonoff's annual benefit show for The Ally Coalition, this year's surprise special guests included Ezra Koenig, Carly Rae Jepsen (who performed an unreleased song!), Dev Hynes, and Jason Isbell.
Koenig, Hynes, and Isbell all banded together to perform 'Married In A Gold Rush', and Koenig also played 'A-Punk' live with an assist from Antonoff.
