Desmond Tutu was, for many around the world, an icon.

Lady Gaga sings the national anthem during the 59th Presidential Inauguration at the U.S. Capitol for President-elect Joe Biden in Washington, Wednesday, Jan. 20, 2021. And country star Garth Brooks, doffing his black cowboy hat, sang a soulful a capella rendition of “Amazing Grace,” his eyes closed for much of the song. While stars mostly eschewed Trump's inauguration four years ago, the A-list was back for Biden. Brooks was careful to call his decision to perform on Wednesday non-political, and in the spirit of unity. Alone with his guitar, The Boss sang his “Land of Hope and Dreams” in front of the Lincoln Memorial.
