Last month, during the second Coachella weekend, Green Day frontman Billie Joe Armstrong joined the reunited Replacements onstage. This past weekend, at Atlanta’s Shaky Knees festival, it happened again. So: Is this going to be a regular thing now? Is Armstrong our new Bob Stinson? Because, if so, that’s pretty weird. Watch video of Armstrong with the ‘Mats at Shaky Knees below.

The Replacements will play Kentucky’s Forecastle Festival in June; maybe some other famous admirer could step up at that one?
