Elvis IS King.

Seriously, folks, if you're going to wait for years to see one of your heroes live, let it be not just as good as, but better than you expected. Let "live" blow the roof off Memorex, so much so that songs you never got that excited about before suddenly become transcendent. Let him surprise you with songs you never thought you'd hear live, and songs you've never heard at all. Let him throw his head back and wail with such passion and power that you get goosebumps. Let him keep coming back on stage when you think it must be over by now because you can't be this lucky, let him play on when you think "surely he'll end with this one", let 3 hours go by and don't even think about leaving your seat for a bathroom break because you don't want to miss a moment of this incredible show. And better yet, surround yourself with hundreds of like-minded folk who make you giggle giddily when they shout out their appreciation, because you feel it too, and by all means, go with a good friend who understands just what you're going on about here.

That's the way to do it.
