Watch Mark Hoppus, Tom Morello, T-Bone Burnett, And Mumford & Sons Play Blink-182’s “What’s My Age Again?” In LA

Here’s just about the least likely combination of rock stars you’ll find on stage together: Last Thursday, a few days after Blink-182’s Mark Hoppus joined Mumford & Sons for a Eurythmics cover, the whole lot of them reconvened at the Troubadour in Los Angeles for a private KROQ show along with Americana overlord T-Bone Burnett and Rage Against The Machine guitar wizard Tom Morello. And as Reddit points out, they played a very sloppy and off-key (but undoubtedly joyous) version of Blink’s “What’s My Age Again?” together. Watch fan-made footage below, and just imagine what Burnett and Morello must have been thinking.

“This is what punk rock is all about.” That’s probably what they were thinking.
