It's one the most enduring tunes from the 2000s and last night The Killers were on hand to give a rousing rendition of 'Mr. Brightside' at the 3 Arena.
RTÉ's Eoghan McDermott captured some footage of Brandon Flowers finishing up 'When We Were Young' before breaking into their most famous hit which we've all belted into at a house party at one point or another following a sherry or two.
Like us, you'll be raging you weren't there and will be vowing to nab a ticket the next time The Killers are in town.
Take a look.
The Killers were stupidly amazing in Dublin tonight. New album strong as hell. Here's Brandon finishing When You Were Young, telling crowd he had to go, before breaking into Mr Brightside as last tune. College years re-lived! Claaaaaaaas night. pic.twitter.com/YHm44VV75b

It's still not the best version we've seen though...
