The 54th Annual Grammy Awards brought a plethora of amazing(and terrifying) performances. For me though, the performance that left the most lasting positive impression was the encore of the night for Sir Paul McCartney and many friends, including The Boss Bruce Springsteen, Joe Walsh, and the original Fighter of Foo Dave Grohl. They delivered an epic performance of the last three tracks(minus the final hidden track) of The Beatles musical masterpiece Abbey Road. It was amazing to see Sir Paul conduct an epic guitar solo-off between the masters of rock that were gathered together to end the Grammy night. What’d you think of this performance?
