17 Throwback Photos That Remind You Of Baby 5SOS

They\'ve been together for 4 years, and oh, how they\'ve changed.

It was four years ago when Ashton Irwin joined his mates from school to make a band in Australia. His friends — Luke Hemmings, Calum Hood and Michael Clifford — had been posting cover videos on YouTube under Luke’s channel, hemmo1996. It was time they made it official — they were 5 Seconds of Summer.

The 5SOS Fam are having a blast passing around old pictures of the guys today in celebration of four years of the band.

Remember when they used to play small shows? I don’t!
