This was the humourous moment a jazz two-piece playing in a Camden venue jammed along with a fire alarm that was being tested on January 17.br br Footage shows a drummer and a saxophonist play along to the sound of the continuous fire alarm.br br The filmer confirmed: "This video was taken in a local jazz bar and features a two-man Jazz Band. br br "The establishment was testing the fire alarm and the Jazz Band joined in."br br The filmer later said: "It was one of those moments where I knew if I didn’t capture it on film, nobody would even believe the story if I told them. br br "Everyone around was at first quite sceptical, especially those that had just walked in - but with most people around dancing, they got the sense that there was no danger and just a really good chance to vibe together.br br Others - who I can only assume we’re regulars - were laughing at the absurdity of it.
