A man who wears many hats, Green Day frontman Billie Joe Armstrong—unsurprisingly—has an incredibly talented family.

Last night (Dec. 19), his son Joey's band SWMRS hosted a charity show at 1-2-3-4 GO! Records. Requiring at least a $20 dollar donation at the door, the show benefited victims of Oakland's Ghost Ship fire, which claimed the lives of 36 attendees to a 100% Silk warehouse show earlier this month. Armstrong's youngest son, Jakob Danger, was also on the bill, along with Ricky Lake.

Announcing the show on Twitter, SWMRS teased some “very, very special guests.”

Well, they weren't kidding. According to the Green Day Authority, Armstrong and Green Day bassist Mike Dirnt joined SWMRS and Danger on stage, performing some deep cuts. Check it out:

“Scattered”

Armstrong is also the singer/guitarist in the punk band Pinhead Gunpowder, alongside Green Day's Jason White. Pinhead's bassist, Bill Schneider, then joined Armstrong on stage at the charity show to perform some even deeper cuts from that usually quiet band.

“Anniversary Song”
