If you are a fan of the music and like what you see on his website, why not give it a try?
I've never heard of him before now. I'm not a big fan of impersonators in the first place, so I'm not the expert here. If you don't want to see old Brandon, there is always the fat Elvis that sings at Bills. They say he's pretty good. Last I heard, it was a free show on certain afternoons. My opinion is that I would rather listen to him while strolling though the casino than look at him. I think the Legends show is pretty good about keeping their Elvis on the bill. I've met him, and he's been doing it for many years on the Legends show.
Elvis Impersonators are a dime a dozen in this town. Some look better than others, some sing better than others. Some dance better than others. Sometimes you see at fat Elvis impersonator in an Army uniform or a skinny Elvis in the fat style glitter cape and scarf outfit with big glitter sunglasses. It was Liberace who made the first flashy cape outfit for Elvis and convinced him to start wearing it, according to my sources.
Pick whatever show you like and have a good time. You can bet that Brandon, Legends, and fat Elvis will have lots of Elvis fans in the crowd, so it will be easy to enjoy.
