YES! I loved Jersey Boys! Frankie Valli and The Four Seasons were the first people I ever saw live in concert, in San Diego at the county fair (it's a pretty big fair that attracts decent acts), so I jumped at the chance to see Jersey Boys.
The lighting was incredibly brilliant. My brother and I agreed that this was the best use of lighting in any live show we'd seen, and we are both musical fanatics.
What a great cast! Did you know that there are only THREE women playing all of the parts in the show? They do a great job! I had no idea!
I saw this show in San Diego before seeing it in Vegas, and my only criticism was that the guy who played Frankie seemed like his voice was a little tired, and somewhat pitchy. Still, the music was top-notch, as was the choreography. The guy who played Bob Gaudio was the same guy who played him in the traveling version that came through San Diego. Watch for him; he's excellent!
If you can see ONE show in Las Vegas, make it Jersey Boys.
