The Oracle on All Good Things (Come To An End)

Q. Did Chris really do this? If he did I love it!
The Oracle replies:
Hmmm well yes and no; they are his vocals. When you see "vs" it means versus and generally means that are two tracks pitched against each other yet spliced together. In this case we have Jay Z versus Nelly's All Good Things.
The latter had an early demo version of the song with Chris not only on backing vocals but the acapella intro that is used here.
What we're left with is neither song in its original form of course, so you can hear samples, vocals looped and repeated etc.

Q. Hi one that knows it all
You mentioned in one of the answers that Coldplay did some sort of colaboration with Nelly Furtado.
When i searched the internet the other day it said that the song All Good Things Come to an End is by both Nelly Furtado and Coldplay. Is this true? And if so, did Coldplay just do the instrumental parts because I never hear Chris' voice.
Thank you in advance!! :)
The Oracle replies:
It wasn't Coldplay, but it was a collaboration with Chris. Unfortunately the version with his vocals didn't end up on her album but it's knocking around on the Internet somewhere. It's a shame because I thought it was a great duet.

Q. Ok is there really something or someone of Coldplay in the song by Nelly Furtado: All Good Things Come To An End?
The Oracle replies:
This is another collaboration that hit trouble when it came to being released. Chris was heavily involved in the writing, performance and recording of this song. Again a version was leaked onto the internet but his vocals were removed from the official release.
