The crowd was amazed at the premiere performance of Quidam by Thursday evening at the Essar Centre.
But before the curtain went up local2.ca cameras were allowed in to take in rehearsals Thursday afternoon.
These people really like to rehearse.
One performer , Tanya Burka, from Vancouver is the rookie of the group. "this is the biggest show I've ever been part of" Burka told local2.ca while on a small break.
The show as you can imagine is enormous. The stage and set up - which is the same size of the permanent shows in Las Vegas takes half a day to build.
The touring show, which runs until May 13 is pretty much sold out according to Jasmyn Pozzo who looked after the public relations for the event.
