It was the bassist of Green Day, Mike Dirnt’s birthday today so Billie Joe Armstrong dedicated today’s “No Fun Mondays” song to him.

“No Fun Mondays” has been Billie Joe Armstrong’s ongoing quarantine music series for the past few weeks.

He wrote in the caption of the video: “This week’s No Fun Mondays is dedicated to the one, the only, Mike Dirnt. Happy birthday! Play this one loud just for him: We’re The Kids In America, originally by Kim Wilde and then recorded later by The Muffs”.

You’ll see there’s another fun touch to the video, a cartoon unicorn bassist, that’s supposed to resemble Mike Dirnt.
