Regarding money
for a dancer (who generally doesn't sing, but lip-syncs to pre-recorded tracks) the payscale starts around 400 and goes to around 700.
For a singer I have heard of as little as 550 to as much as 2000.
I worked as a singer for Celebrity in 2003 and 2005 and I made 800 for my first contract. I negotiated my second contract and got 1100 a week. On celebrity I had no cruise-staff duties and I had my own cabin. I had full guest privelges.
If you like singing and want to make some easy money and see the world, it's a great job. The shows are very light in terms of content-it is really just one huge concert with flashy dance. If you really love Musical Theater, you might not enjoy it as much.
i know i was dying to just say one line of dialogue for the whole contract. I have much more fun exploring a character in a show and getting to the reason WHY they sing, than just standing in front of a bunch of overfed tourists singing Music of the night wearing a phantom mask and a pink sequinned cape (I swear to GOD!)
Other than that, did you enjoy the play Mrs Lincoln?
