Australian heartthrobs 5 Seconds Of Summer have unveiled an exclusive behind-the-scenes video from their recent two-night stint at London's O2 Arena on their Sounds Live Feels Live tour. 

The clip, which is just under three minutes in duration, shows the lads rehearsing for their concerts, messing around in the dressing room and performing live on stage in front of around 20,000 fans. 

Guitarist Michael Clifford told his followers on Twitter this week that there's nothing more rewarding than being on tour and playing in front of thousands of supportive followers night after night: "Just wanna keep playing shows and never get off stage. Thank you for tonight, Leeds. Nottingham is up next!"

Speaking to BBC Radio 1 recently, the boys admitted that they just want to give fans the best time at their gigs: "We're super inspired by old-school rock bands and stuff. We pay a lot of attention to bands like Queen, but we're very interactive live. It's not just about us playing songs, it's how can we get you guys in on the jams as well."
