Green Day frontman Billie Joe Armstrong shocked Saturday night drinkers in a north London rock bar last night (May 13) by jumping onstage to sing Basket Case with a disbelieving covers band.
Clearly a surprise to all involved, Armstrong's spontaneous guest spot with covers band Borderline Toxic at Slim Jim’s Liquor Store on Upper Street in Angel, north London was documented on social media: the band posted their own footage of the performance of the Dookie-era classic on Instagram, with the caption: 'The moment your band gets joined on stage by your childhood idol to sing their own song with you… in your favourite dive bar!! 🥹 Billie Joe Armstrong… @greenday !! THANK YOU, YOU LEGEND! 🔥 This was the first band to get me into rock when I was 11 years old and I’m honestly just so made up 😅🥹 brb crying/screaming/spewing'
Green Day's most recent London gig took place in front of 75,000 fans at the London Stadium last June, as part of their Hella Mega Tour.
