Gavin James is playing a "secret" gig in Dublin today.
He posted a video on his Facebook page earlier inviting people along to the Old Storehouse at 4pm.
But he says there is only room for about 50
"I'm doing a little gig at 4pm in the Old Storehouse at 4pm," he told his fans.
"It's gonna be great craic. It's first come, first served.
"It's for pre-record for some tv. I've been sick all week, feeling a lot better now.
"Let's do it!"
