Gosh, I go to the trouble to set up a "Disney Music Block Party Tour" tag, and Gwyneth notes today that most of the tour dates have been cancelled. Only the Long Island show is still on. Just my luck.
The ticket prices did seem a bit high (though you were getting a lot of music and other stuff for those prices), so perhaps attendance was an issue. Or maybe karma for not venturing west of the Mississippi.
If I find out something else, I'll let you know...
Update: This from AEG Live, via Disney -- "Due to unforeseen circumstances, The Disney Music Block shows at the (name of building) has been cancelled. We are sorry for any
inconvenience and refunds are available at the point of purchase."
Doesn't really answer much, does it?
