By Karena V. May 10, 2021 Global Citizen aired its Vax Live: The Concert to Reunite the World on Saturday night and some rock acts stood out! Eddie Vedder kicked things off playing two songs with Josh Klinghoffer of Red Hot Chili Peppers assisting. Foo Fighters took the stage for a six-song set that included some help from AC/DC's Brian Johnson for a cover of "Back in Black." The show was filmed last weekend but aired on Saturday night.
