Adele and Jennifer Hudson really nailed it.
Also enjoyed - Bruce, Maroon 5, The Beach Boys... Katy Perry rocked it, but the blue hair was a bit much. Why a gorgeous brunette needs to go blue
...maybe an ABM Camaro fan? Enjoyed Jason Aldean & Kelly Clarkson's duet until his mic died.
Nice to see Glenn Campbell, and nice of the audience to give him a standing O... except for the two skanks in the audience that the camera caught sitting there texting. I guess they were bored, probably never even heard of Glenn Campbell.
...and Chris Brown... Madonna can lip sync better than that tool.
Overall a great show.
