Joni Mitchell's surprise performance at the Newport Folk Festival on Sunday is already becoming the stuff of legend. The unsuspecting crowd roared as the singer-songwriter stepped onto the stage in her first public performance since suffering a debilitating brain aneurysm in 2015.
And they continued to revel as the nine-time Grammy-winning singer regaled the lucky audience with many of her most beloved songs, including "Big Yellow Taxi" and "Both Sides Now," as well as a cover of "Summertime."
