The Rock and Roll Hall of Fame: 10 highlights from the 2015 induction ceremony

Paul McCartney Shouting “Oi!” During “American Idiot” 

Green Day’s three songs were all pretty great (“When I Come Around” remains one of the five best songs written in the entirety of the ’90s), but there was a particularly charming moment   during “American Idiot” when Armstrong encouraged the crowd to shout “Oi!,” a classic punk rock exclamation. They cut to the crowd, and while not a whole lot of people were actually participating, Paul McCartney was not only doing it, but he was also encouraging other people to do it, proving Paul McCartney should be invited to every party.
