It's safe to say that the 2017 Lions tour of New Zealand exceeded expectations on this side of the world, as a series that was seen as a very difficult task for Gatland's men produced three outstanding test matches in which an outright winner could not be decided.
Over the course of six weeks we saw some players grow into the jersey, but considering many had him omitted from their predicted Lions tour squads all year, few made as big an impression as Sean O'Brien.
The Leinster man proved that despite his injury issues he is still one of the most influential players you can put on a rugby pitch, so now that the tour is concluded, he can enjoy a few beers and look back on a job well done.
Thankfully, Conor Murray was on hand to actually film his enjoyment of those few beers, and the resulting clip of O'Brien belting out Westlife surrounded by his Lions teammates will bring a smile to every Irish rugby fan's face.
There's something about the mixture of sport, beer, and Irish people that often results in Westlife being sung at the top of the lungs.
O'Brien's own Instagram story further proves that he's enjoying himself out and about in Australia too.
