Very enjoyable show. I attended on January 11th, which was one year anniversary of their show. It's tough for a new show to survive in Las Vegas, and they made one year mark, which tells you something.
All the singers (from UK and Ireland) are great, but especially, I liked Johnny, the one with long curly hair. His voice was so beautiful. There a Capella version of "Phantom of the Opera" was great.
One thing that can be improved is that they have 2 guitar players and a drummer in the band, but no keyboard/piano player. They play a pre-recorded track for piano and keyboard. If they had a live piano player, the show would be more exciting!
