Eugene Weekly's Entertainment reporter is covering the Annie rehearsals on her blog. She put up these two videos.
First one is Annie singing "Maybe" in rehearsal, and Jaya (the other Annie) singing "Tomorrow":
Then a tour of the whole operation, with Asa trying on the dreaded curly-mop Annie wig at the end. She has since decided just to dye her own hair red and has been given a promise that she will NOT have to wear this wig!
