She (Christine) has been known to sing some of Stevie's songs in rehearsals. There's also a version of "Dreams" from the Mirage rehearsals with Chris on vocals and i have the Rumours rehearsal cd with Chris doing vocals on "Dreams" and "Rhiannon" and Lindsey takes over for "Landslide" and "Gold Dust Woman"...It's either cause they were sparing Stevie's voice or they were just doing a technical run through and didn't really require Stevie at that point in the rehearsals.

The performances tend to be funny at times. During "Rhiannon" Chris sings "da da da da da da da...." in place of "Rhiannon rings like a bell through the night..." and she actually does part of the full on ending. She says something during the ending of that i can't quite make out. Anyone???
