Aretha was GREAT! She still can mesmerize me and at 72 yrs. old, still has the pipes. AS for Cissy Houston "singing" background..umm... WHEN did she actually do that? It seemed like she hit the liquor cabinet before the show. But even Cissy couldn't ruin this performance of Aretha's. I just wonder why she never went back to Letterman, though it could have been her health. He did invite her back though..seems like something was off between them. Oh well Dave's loss.
