Shrooms - song in the credits

[SYLiam]

Hey, I work for Odeon cinema, and was cleaning a screen the other day after Shrooms had finished, there was this rocky song with a chick on vocals - thought it was pretty catchy, but didn't actually watch the credits to see who it was.

Anyone know who it may be? cannot remember any vocals, or anything, but the music was pretty awesome.

Thanks!
