Saw some comments on another board that Chris might be singing "Night and Day". Could be a decent song for him.
Looking through the song list, I think "Let's Fall in Love"(about as youthful as there is in that song list) for Paris and "Blue Moon" for Katharine could be pretty good for them in addition to the songs I favored in the previous post. Hoping Katharine will pick something that will keep her out of her wailing/screeching range.
It should be fun tomorrow night.
I'll be sad to see any of them go. Each one has something special to offer.
