Brandons Big Birthday PLANS!!! HELP!

Brandons birthday is coming up in about a month and I need ideas of what to do!! I've thought about going to dinner and a show down on the strip. But I dont know what one to take him too. I've considered 'KA' or even 'Phantom of the Opera'

but i'm not sure what he would like best. So I need some help. For those of you who dont know him, he is very musical and very...well I guess the only word to use would be layed back. So I know he would be happy with either one as long as he gets a good stake in his belly before hand ;) Please HELP!!!
