Stand-up comedian Ian Cognito died on stage after suffering a heart attack Thursday.
According to the BBC, the 60-year-old “sat down on a stool while breathing heavily before falling silent for five minutes.”
Cognito was pronounced dead at the scene.
He had been performing at The Atic bar in Bicester, with compere Andrew Bird admitting the crowd thought it was all a joke at first.
Mr. Bird said Cognito hadn’t been feeling well before the gig started, but was adamant the show would go on.
Bird shared: “He was like his old self, his voice was loud. I was thinking he’s having such a good gig.”
“Everyone in the crowd, me included, thought he was joking. Even when I walked on-stage and touched his arm I was expecting him to say ‘boo.'”
Audience member John Ostojak continued: “Only 10 minutes before he sat down he joked about having a stroke.”
“He said, ‘imagine having a stroke and waking up speaking Welsh.'”
Tributes have been pouring in for Cognito since the tragic news emerged online.
