The Chainsmokers and 5 Seconds of Summer have been putting on electrifying live shows on their World Woy Joy tour and if you weren't lucky enough to catch them in person jamming out together, this is the next best thing! Luke Hemmings nails the live vocals, Ashton Irwin joins Chainsmokers resident drummer Matt McGuire to shred on their drumsets, and Drew Taggart kills it on backup vocals & guitar. Absolutely worth the watch!
