Just a question :

You have the money for a concert, you think naturally you gonna see Bon Jovi, and there's an info on the cover of every magazine : Bruce and the E Street Band for the last time.
What will you do ?
Just stay on you project and no question to miss BJ, or the last chance to see the others is really something, so you change your plans and you'll see BJ later, (but maybe next year ...),
