As you probably already know, in Vegas you can even get married by Elvis. I was there about two summers ago and one of the not so famous casinos had a "Big Elvis" perform every afternoon at 2 & 5. Everytime I walked by that casino they'd be advertising Big Elvis. I never went to seen him, but by the picture, it seemed to be a fat guy with a jump suit and sun glasses.

Then again, he may have been pretty good. I've never known Vegas to have any unprofessional/amature type acts, at least not on the strip.
If you ever come to America, I'm sure you'd love to visit Vegas. You can get all kinds of Elvis souveneirs as well.
