WATCH: Sean O'Brien and his Lions team-mates joyously belting out a Westlife classic
The Lions were out on the town on Saturday night after a gruelling six weeks in New Zealand, and it looks like they were hard at it.
We've all seen the videos of a boisterous Ben Te'o proclaiming himself and Johnny Sexton as the best 10 and 12 that Ireland has ever seen.
Slightly debatable, Ben, but, we'll let you off with that one.
Well, it seemed like it was all a bit too much for Sexton. Maybe the non-stop action of a tough six weeks Down Under had taken its toll on him.
Sean O'Brien was showing no such ill-affects, despite his thumping collision with Jerome Kaino during the drawn final test, which forced him to be withdrawn from the game.
O'Brien was back at it on Saturday night and he appeared in great spirits.
The Carlow man was leading his Lions team-mates in a rousing rendition of Westlife's ageless ballad 'World of your own.'
The 30-year-old was like a wild country man belting out the tunes in the middle of a Coppers Tuesday dancefloor.
Leigh Halfpenny, get off your phone and appreciate the songbird of Irish rugby.

Sean knows the score.
Someone get that man a pint of Guinness, it's what he wants.
