Why Mick and Stevie?

[Villavic]

Has anybody ever read about WHY they chose Mick and Stevie to appear at the Rumours cover? I mean why just those two, why not Mick and John again, or why not the 5 members, or Mick and the girls, or Mick and Chris (that would be again a Fleetwood and a Mac, like in the previous album).

Mick's book describes the cover but not the story behind it.

The cover depicted me and Stevie in our stage clothes, she in black chiffon and ballet shoes, me with my wooden balls hanging. In my left hand I hold the same crystal ball juggled by McVie on the cover of Fleetwood Mac.
