Probably a silly question to most of you, but i'm new here so can hopefully get away with at least one silly question

I'm going tomorrow for the last night. I went on the 8th and had a great time. Took clients with me who all decided to dress up in ridiculous outfits, which was very embarrassing..... Anyway, I digress.

My question is: What is the final night of a tour generally like?

Is it a party atmos? Do the band generally put on a longer show? Shorter show? A better show? Worse show?
Is it a time for them to let their hair down? Or will they be tired and jaded?

As I say, I'm going again tomorrow - not with clients this time and I know none of you can give a definite answer, but a lot of you seem to go to a number of shows, so was hoping you might be able to at least give an indication.

Many thanks in advance.
