The Chain came from Butter Cookie Keep Me There?

[Dreamz19]

I was looking through the songfacts website and stumbled upon a comment that was listed under the facts section.....that said

"This began as a Christine McVie song called "Butter Cookie (Keep Me There)," which which is available on the expanded edition of Rumours. The beginning of the track wasn't working, but the band loved Mick Fleetwood and John McVie's ending, which was now on tape. So, they counted back from the bass line, used the kick-drum as a metronome, Nicks gave them the lyrics for the verses, Buckingham and Christine McVie wrote the music and the chorus lyrics, Lindsey added the guitar over the ending, and "The Chain" as we know it was born."(thanks, Kazryn - Potters Bar, England)

Does anybody know if there is any truth to this? I've never heard this before or read it anywhere, but I remember that I had downloaded a intrumental version of "The Chain" a year ago and it was labled "Keep Me There." Thanks in advance.
