Dave Grohl

Dave Grohl and his Foo Fighters play badass grandpas who rock out at their retirement home, thus starting an elderly riot.

PS: Stay tuned for the choreographed dance at the end.

Take one of the greatest songs ever and invite Pharrell Williams, Emeli Sande, Elton John, Lorde, Chris Martin, Florence Welch, Kylie Minogue, Stevie Wonder, Brian May, Jake Bugg, One Direction, Chrissie Hynde, Jamie Cullum, Dave Grohl, Sam Smith, and many others to join songwriter Brian Wilson in the most epic group since "We Are The World." The fact its coupled to an ambitious and stylish video directed by Francois Rousselet, of Jonas & Francois, that includes every single performer in uniquely appropriate set-ups makes it all the better — and yes, there's a charitable tie-in.

PS: How is Bono not in this??
