In a recent collaboration with U2 on "The Saints Are Coming," Billie Joe Armstrong of Green Day sang about a house in New Orleans. But he spent this weekend hammering soffit onto one, as a volunteer with Habitat for Humanity. Armstrong brought along some friends and his fam to help with the project as well, and they’ve been blogging about the experience on the Green Day fansite.

On a semi-but-not-really-related note, Green Day is continuing to work with NRDC on a campaign to Move America Beyond Oil. Below, the latest video installment on the site, this one featuring Adrienne Armstrong (Billie Joe’s wife). Note all the young people who’ve joined the campaign — all the cool kidz are doin’ it!
