It's been more than two years since Fun.

last played Glasgow, in a sparsely populated Art School bar. They've upscaled their crowd somewhat since then, thanks to their huge, record-breaking hit We Are Young. While some seem to have flocked to the ABC this Monday night solely on the merits of the hits alone, most appear to have delved a bit deeper into the band's musical offerings. Fun.'s playlist often harks back to their 2009 album Aim & Ignite and the bopping crowd are clearly familiar with it, especially their should-have-been-breakthrough-hit All The Pretty Girls.

The set opens with Carry On, a gentle starter with a big chorus. But the party really feels like it's begun when the big, stomping intro of One Foot kicks in, with frontman Nate Ruess bounding around the stage, punching the air and making faces only a man completely consumed by his art would pull. His breathtakingly bold and reliable vocals are in a different league from almost all of Fun.'s contemporaries, while the passion and energy in his delivery place him comfortably among the world's best.

Guitarist Jack Antonoff is similarly gripping to watch, battling with a red guitar that appears at times to be alive and fighting back, such is the movement and the glorious wails that come from it.

Unsurprisingly, We Are Young gets an incredible reaction and a magnificent singalong, but it's Some Nights, which echoes out at the end-of-set closer that brings the biggest smile. You can see in Fun.'s faces that, even for a band of their recent calibre, the Glasgow crowd has left them a little stunned – and the feeling is mutual. Fun? What an understatement.
