During the encore of his headlining set at Lollapalooza last night, Sir Paul McCartney brought out Alabama Shakes frontwoman Brittany Howard to assist on “Get Back.” Howard played guitar and sang harmonies and even took lead on the second verse. And in addition to his setlist of Beatles and Wings classics, Macca also busted out a bit of his recent Rihanna/Kanye collab “FourFiveSeconds,” taking over Rihanna’s vocals before segueing into “We Can Work It Out.” Watch fan-shot video of both performances and check out the full setlist below.
