Introducing the song, drummer Tristan Evans explained the British pop rockers had performed the song during their U.K. arena tour this past spring but this was the first time playing it since. 

At one point in the middle guitarist and singer Bradley Simpson announced, "Acoustic rock everyone, here we go," getting a bit of a chuckle from his typically plugged-in bandmates. But on this side, everything sounded solid.
