For this song, Swift wanted to replicate the sounds of the songs Jacknife Lee has produced for the likes of U2 and Snow Patrol. So not only did she recruit the latter band's lead singer, Gary Lightbody, to co-write and duet with her, but she recruited the producer himself to helm the whimsical orchestral ballad.
Gary Lightbody is one of several songwriters that Swift reached out to write with her on Red. She told Billboard magazine that the people she chose to collaborate with were ones who inspired her. "Snow Patrol are so absolutely dead-on," she said, "they can just hit you when they are singing about loss or longing."
