I just stumbled across this. It's from 1981 "Bob Welch and Friends Live at the Roxy". Stevie Nicks and Mick Fleetwood sitting in with Welch's band, and they do Gold Dust Woman. I think it's just great...Fleetwood seems to be having the time of his life, and I'll betcha it's from the period where he and Stevie Nicks were sharing a bed.

If anybody's interested, the whole concert is on YouTube at:

And the video quality is way better.
