29 years ago....

Mick Fleetwood phoned Stevie and Lindsey asking them to join FM....

i have a few questions about this:
1. Why did Mick choose New Years Eve to call them?
2. What was everyone doing that day?
3. Who answered the phone? Was it Lindsey? Did he say, "hold
on..." and then tell Stevie?
4. Did they say yes right away?

I was under the impression that they didn't say yes right away...Lindsey wasn't ecstatic about the idea at first, which leads me to believe that they had to tell Mick they'd think about and get back to him....was this when Stevie went out and bought all of the FM albums and decided that they actually could add something to the band without taking away from their own style?
