Glen Campbell was the man of the hour last night. At the 54th Annual Grammys, the entertainer was honored with a special tribute on stage with Blake Shelton and The Band Perry.

The Band Perry performed "Gentle on My Mind" and Blake Shelton, who was a Grammy nominee, sang "Southern Nights." Then Glen Campbell himself came out and performed "Rhinestone Cowboy," beautifully.   There was no hint  that he has "Alzheimers" during his amazing performance.

The audience was on their feet for  Campbell  remembering just why they loved the entertainer.  With the whole audience signing along, it was a picture perfect moment that reminded the world how important music is.

Campbell was diagnosed six months ago as being in the early stages of Alzheimer's disease. With his final album, "Ghost on the Canvas,"  and his final tour, "The Goodbye Tour" this will be one of the last times Campbell will be on stage in front of a national audience.

He performed in Bossier City just a few weeks ago.

Blake Shelton, who was also a Grammy nominee did a fabulous job with Campbell's "Southern Nights."  And the Band Perry couldn't have been any better playing the huge hit, "Gentle On My Mind."
