Gavin James is playing a "secret" gig in the capital later this afternoon.
He's inviting people along to the Old Storehouse in Temple Bar at 4pm.
He posted a video on his Facebook earlier -- but he says there's only room for about 50.
"Need fifty of yiz to come, it's gonna be great craic -- first come first served," he said.
"Gonna do some songs, gonna have a pint of Guinness... I've been sick all week, feel a lot better now, and I'm ready to do some songs!"
