Jonny, I should have pinged you to what I just posted to doodlelady. You're right, of course, but I simply don't think Chris is capable of doing anything else. For example, I can't see him doing a gentle ballad or even the song Taylor sang last night. I don't think he has the voice for it or the personality.
Speaking of personality, McPhee seems increasingly creepy to me. BTW, have you noticed that as every show is ending, Pickler runs straight over to McPhee. I hope it's just a schoolgirl type bonding thing going on between them, and not something else.
If it is something else, I still won't believe it until I see the video evidence. Repeatedly.
