George Wallace's "I Be Thinkin" is a great show. A friend took me out to it and I heard a Yodeling version of "Milkshake" sung by six guys who use their voices to do all of the instrumentation: Mosaic. They opened for George Wallace. George Wallace is as funny as I remember and it is a different show every night because he interacts so much with the audience and plays off of them. I highly recommend it to anyone that comes out to Vegas. It is a late show at 10PM, so if you are coming from the Midwest or east coast, you might not go on your first or second night here or you might be fighting to stay awake. :D
