There really isn't a storyline - I mean, in the program and on the site, etc., they SAY there's one, but they don't really execute much of one in the show - it's all pretty random.
If you like Disney songs, are up for new ways of playin' around with em' (lotsa medleys and such), aren't looking for theatre but something more along the lines of the showchoir type shows at amusement parks, and are up for hearing some pretty amazing voices, then I'd reccommend it, but only if you get the cheapest tickets or can get a big discount or free, etc. Otherwise I'd just buy the cd.
The other thing - when I saw it, it drove me crazy that the audiences here in Cleveland interpreted it as such amazing theatre rather than taking it for what it was - if you have the tolerance to hear people rave about it and how amazing it is while other truly amazing shows can't even sell tickets...then go, lol.
If I show you the darkness I hold inside, will you bring me to light?
