Green Day onstage in Milan
"True story: our boys Green Day came to our show in Milan and decided to play a few tunes. #ThisIsHappeningRightFuckingNow"
Apparently, Mike tipped us off earlier today in this post on his Instagram.
We'll update this post as we learn more about the show...
Update 1: We've added the show into our tour section. As we get the setlist and photos, they will be posted there.
