(Louder Sound) - Green Day fans were left heartbroken as the band pulled the plug on their scheduled appearance at London's Electric Ballroom tonight (Friday).

Just a day after the punk heroes performed a surprise show for around 100 fans at the Marquis pub in Covent Garden, they were due to perform at the Electric Ballroom in Camden.

The show was part of the band's intimate Hella Tiny tour, with the 1200-capacity Electric Ballroom a far cry from the venues they are used to playing.

But with fans already lining up outside, Green Day announced via a social media post that the gig would not go ahead.

On X (formerly Twitter), they said: "London, unfortunately tonight’s show has been cancelled due to an unexpected illness.

"We're truly bummed about this and apologise for any inconvenience caused. Ticket refunds will be processed automatically next week. We’ll see you back again on The Saviors Tour if not sooner."
