I went and saw Christopher Cross there last night and plan on going to as many of these as I can. The theater is great - no bad seats. And it's awesome to be able to experience some of these old school performers while they are still embodied!!  

And don't throw your ticket stub away... on the bottom is free entrance to Gold Diggers which has an awesome balcony overlooking Freemont Street.  

I love old town... such a classic, different vibe to the Strip..
