The band dropped by the BBC Radio 1 Live Lounge where they slowed the pop song way down, even sampling the Ben E. King classic, "Stand by Me."
As the radio host pointed out, "I love the sort of barbershop quartet harmonies in there. It sounded so old-school... I was imagining an old American prom scene in a film."
The guys joked that they are in fact, available to sing at high-school proms. (We wish.)
