"Walking After You" is a 1998 single from the soundtrack album to the X Files movie. The Foo Fighters re-recorded the song, which originally appeared on their 1997 album The Colour and the Shape, specifically for the movie's soundtrack. While none of the X-Files album songs are prominently featured in the movie itself, "Walking After You" is played during the end credit sequence, following Noel Gallagher's "Teotihuacan." The single's B-side is Ween's "Beacon Light."
Foo Fighters had previously contributed a cover of Gary Numan's "Down in the Park" (1979) to the compilation album, Songs in the Key of X: Music From and Inspired by the X-Files (1996). Foo Fighters frontman Dave Grohl is an avid "X-Files" fan.
Before the song's release as a tie-in to the movie, another song off of The Colour and the Shape, "Hey, Johnny Park!," had been slated to be that album's fourth and final single. Although recorded for the X-Files soundtrack, "Walking After You" is also considered an official Foo Fighters single.
The song was performed during the Foo Fighters' acoustic tour, and can be found on the live concert CD and DVD, "Skin and Bones" (2006).
