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.

Let's reminisce...
