Watch The Alabama Shakes' Brittany Howard Perform "Get Back" With Sir Paul McCartney

via Twitter

Friday night, in the midst of his Lollapalooza headlining set, Paul McCartney brought out Brittany Howard of Alabama Shakes for a rousing performance of "Get Back," The Beatles' classic late-career single. Given Howard's fiery blues sensibilities, the feature was a perfect fit, and the duo harmonized with great success before Howard herself took the helm for the second verse. McCartney also performed portions of his Kanye West and Rihanna collaboration "FourFiveSeconds" while at Lolla. Watch video of both moments below.
