When You're Gone - Acoustic Version

Avril Lavigne was married to Sum 41 lead singer Deryck Whibley when she wrote this song. In "When You're Gone," she expresses how she feels when they are apart, something that happens a lot when they are each touring.

Avril wrote this with Butch Walker, who also produced the track.

Lavigne told MTV News that she didn't deliberately set out to write a love song. She said: "I was writing a slow song and that just brings out all that stuff in you, all that emotional stuff. It's not cheesy, because I wrote it. If I was older, a professional writer coming up with all that, that would be lame."
