THIS IS AN ABSOLUTE MUST SEE IN LAS VEGAS.
I've seen his show a number of times and have never been disappointed. Its always awesome and a really fun time. Forget about the big aspect of his show, he is a super friendly and approachable guy that sings the songs spot-on and makes it really fun for everyone there. Is he the best Elvis impersonator in Las Vegas? Who knows. He is by far the funnest and most genuine act I have seen to date. I would gladly pay to see this act but its actually free. At the time of writing this, he was performing at the piano bar at Harrah's on Mondays, Wednesday's, and Friday's at 230, 330, and 530.
Do yourself a favor, see this show. Meet the guy, Shake his hand. Take a pic with him. And leave him a nice tip. Its well worth it.
