The Who -- Any suggestions?

So does anyone have any thoughts as to how I can persuade my husband that I should leave the family thanksgiving weekend (inlaws, kids, daughter-in-law, etc.) early, and spend the Sabbath in Philadelphia with my youngest son so we can go to "The Who" concert at the Wachovia Center on Saturday night?

I didn't think so.... :-(

I don't suppose anyone has any inside knowledge on whether they are going to extend the tour to make a stop in the Washington area?
