Whose voice is that in the intros?

[Villavic]

I always wondered who is the guy who says Ladies & Gentlemen... please... Welcome Fleetwood Mac, in the 70s concerts, since the first time I heard him at the Live 1980 album before Monday Morning. But he is also in Intro at Rumours Expanded 35th anniv., Intro (Live At Wembley, 6/26/80) at Tusk Deluxe, and some bootlegs shared in the past.

Not sure if it's the same voice at the deluxe white album (Get Like You Used To Be -Live at Capitol Theatre, Passaic, NJ, 10/17/1975), but I think it is. Does anybody know who is? It doesn't sound like Lindsey.
