Green Day were in Philadelphia on August 9th for a tour that's celebrating 30 years of 'Dookie' and 20 years of 'American Idiot.' They played both of those albums in their entirety, plus a ton of hits and a few new songs, too (36 in all!). 

Backstage at Citizens Bank Park, in an extended conversation with Pierre Robert, Tré Cool talks about Green Day's place in pop culture, from their link to Deadpool & Wolverine to working alongside Mark Hamill in new video for "Corvette Summer." He shares stories of drumming alongside not one, but two Beatles, plus the time he jammed with Willie Nelson: "Willie's asking you to play drums; who cares how high you are?!"

Tré also reflected on the way that Green Day's audience has grown up with them, and how the band are feeling better - and closer - than ever before. And it's clear that they love coming back to Philly, as they've been doing faithfully since '93.

Take it from Tré: "It’s nice to be on America's finest, curated-by-hand rock and roll radio station: WMMR!"
