Post Malone is playing Longitude next month but he’s already given Irish fans a bit of a treat.

The rapper’s been filmed singing The Auld Triangle, a song made famous by The Dubliners.

The bizarre incident happened when Irishman Darragh O’Rourke, who’s on a J1, went to a Post Malone gig in LA and ended up backstage with the man himself.

Darragh didn’t even have a ticket but somehow managed to get in, hang out in the 22 year old’s dressing room, and convince him to sing an Irish tune.

What’s even weirder is the fact that Post knows all the words!
