Hi cedge !
While I can't answer your query I'm sure one of the forum members who has attended the show will be able to give you some definitive advice.
On the assumption that you go to the show could I ask if you would be prepared to provide a spoiler for the people on Digital Spy. If you are OK with this, could you pm me (send me a personal message via the forum) to arrange this! You'll have the appreciation of millions (well hundreds!) on here!
I will fully appreciate it if you don't want to do this - but either way I hope you get there and have a great time. Do post to let us know how the night went!
Cheers.
