I had front row seats to Cats in San Francisco years ago. It was almost too close, as it was hard to take in everything at once, and we had to look up. It was still pretty incredible even though my neck hurt for a few days afterwards.
I really enjoyed the Stage version of Phantom of the Opera:
I'm surprised the tickets aren't more expensive - you are offering a great deal for someone. Believe me, chicks dig Andrew Lloyd Webber shows...
