Glen Campbell may be battling Alzheimer's, but he showed the Grammy telecast's other performers how to do it with his rousing, lively performance of "Rhinestone Cowboy." He strutted across the stage, he let the crowd participate in the song and he seemed to be having a grand old time with backup performers the Band Perry and Blake Shelton. Unfortunately, a sad reminder of reality sneaked in at the end of the performance as Campbell's hot mic picked up the confused singer wondering aloud, "Where do I go? Do I go somewhere?"
