Production and history
Gary Lightbody, frontman of Snow Patrol, stated it is the "most pure and open love song ever written." The phrase "Chasing Cars" came from Lightbody's father, in reference to a girl Lightbody was infatuated with, "You're like a dog chasing a car. You'll never catch it and you just wouldn't know what to do with it if you did."[5]
The song was first heard on the band's 2005 Final Straw tour, when they began playing it, along with two other newly written songs ("Your Halo" and "It's Beginning to Get to Me") they had intended to release on their upcoming album. Since then, the composition of the song was changed slightly, and most of the lyrics were rewritten.
