@JR...
I sympathize with the predicament you are in. However after returning from the mountain top and channeling BOTH Jimmy Swaggart and Pat Robertson, I have to unfortunately report that Jehovah will not be moved. End of the world will happen on September 23rd as announced.
Not that I don't feel sorry about your Arcade tickets. I am in about the same mess over the less than ideal timing.
Good friend of mine, bass player, vocalist, song writer is turning the big 50 on the 23rd. Nicest guy. He is independently wealthy from inheriting a toilet manufacturing empire and spares no expense in celebrations. The party has some international cello player being flown in. Catering from hi end establishments. Finest alcohol will flow like rivers. Beautiful people from everywhere will be there to celebrate in his ocean front mansion. Even pick up and drive home in limos in case we get too drink to drive.
The only recourse we have is to convince both Arcade and my buddy to move the festivities to the 22nd. As it stands right now, the timing could not be worse.
