Green Day's Billie Joe Armstrong and Rancid's Tim Armstrong have the same last name, so what the hell else are they gonna do besides start a band together called Armstrongs? As Spin points out, their new supergroup together also features Billie Joe's son Joey and Tim's nephew Rey -- that's a whole lotta Armstrongs! -- and they just released their first-ever song together called "If There Was Ever A Time." Proceeds from the single will go towards Bay Area punk staple 924 Gilman where both the Armstrongs big bands got their start. You can listen to it below and order a limited-edition flexi-disc here.
