At tonight’s Grammys, Mumford & Sons were strum-a-strum-strummin’ their way through “I Will Wait,” and the camera found its way to Taylor Swift (as the camera often does), and she was having a good old-fashioned singalong in her seat. Mumford & Sons were doing a duet and they didn’t even know it! Had they known it, they would want the moment to last forever. And now it can, thanks to GIFs.
