London Grammar got signed as a result of this song written by their vocalist Hannah Reid. Guitarist Dan Rothman explained to The Sun: "We got signed before we'd done any major touring. Some bands tour beforel, but we were signed because of Hannah's voice. Very few bands are signed without touring, with no fanbase or buzz. Hannah had written a song called 'If You Wait,' which was incredible – that was the reason."
Reid explained the background to the track: "An unnamed person inspired that song," she said. "I was just thinking about how weird it is that humans have that urge to find another person. It would be much easier if we didn't."
Hannah Reid hates singing this song live. "I can't breathe properly during it, for some reason," she explained to The Independent. "It makes me very anxious, when I know I have to sing it."
