My Chemical Romance "Sister To Sleep" (Lost/Unreleased Studio Recording)

In 2003, while recording the Manhattan Demos for the album "Three Cheers for Sweet Revenge", My Chemical Romance recorded a track called "Sister To Sleep". It was never officially released to the public, but was performed at a live show sometime in that same year. As a result of this, a live bootleg has unofficially circulated onto the internet, and is available to listen to on YouTube. However, the studio version remains lost, even to the band members themselves.
