I've had the opportunity to see this show several times and never tire of it! No such thing as a bad seat though I prefer sitting a bit towards the back. The music selection isn't quite a "best of" collection which adds to the enjoyment and keeps it from being predictable while being excellently mixed.
If you have the opportunity, see it. You don't need to be a Beatles' fan as much as a music fan. The dance numbers, though offbeat, are matched with their musical tracks very well. Quickly paced with very little drag it makes for a great evening of entertainment.
