The Chain Solo?

[markolas]

I have an mp3 of what appears to be a live solo performance of The Chain by Stevie. But, I've never known it to be a part of any of her solo tours, so I suppose it could be a Fleetwood Mac performance. I definitely hear "the girls" on background vocals, and there's a male vocal on the ending "running in the shadows" part, but it's definitely not Lindsey, Rick Vito, or Billy Burnette. He sounds like an R&B singer, whoever he is. Has anyone heard of this?
