More from Dennis at the CMA Awards in Nashville: He got in late in the afternoon yesterday, and made his way to some media events and partying. For tonight’s show, he reports that "My sources tell me there will be two surprise appearances, one as a performer and one as a presenter. I promised to keep a lid on it, but I can say that the surprise presenter is a much-missed artist who’s been laying VEERY low for several years. Sign of a return to the Nashville hit parade? We’ll see. I promised not to say anymore — so check out the show tonight"
