After the first two stops, the tour appears to have settled on using local TV and radio personalities. There is a page listing the celebrities in each city, so I won’t list them all here.

Presumably, the celebrities are doing their own singing, but a lot of the songs are being reused; three celebrities in a row sang Shania Twain’s “Man! I Feel Like a Woman.” I am still trying to figure out if the non-celebrities, which are never revealed (not even at the backstage meet-and-greet), are doing their own singing or not.
