It looks like joining in on an Irish pub session is the new craze - last week it was Liam Gallagher, this week it was Step Brother star John C. Reilly.
The Guardians of the Galaxy actor made a guest appearance at the Galway Film Fleadh in early July and has been holidaying on our shores with his family since - so he knows how things work, especially in famous Clare pub Gus O’Connors.
Donning a traditional flat cap and a lovely Irish summer jumper, he didn’t shy away from the phrase most of us dread, “John for a song”.
Having starred as Amos Hart in the smash-hit movie Chicago in 2002, we all know he’s well able to hold a tune.
And just to put the icing on the cake, he treated the crowd to a renidition of 'Wild Rover'.
