I don't know if they unveiled anything new or not, but at the New Orleans concert Sting introduced a song saying "I wrote this in 1784- at the battle of New Orleans" or something similar (that's not a direct quote) and then went on to play an early police song but I can't remember which one. I took it as basically just a joke that it seemed like a very long time since the material was written. At that time, it definitely was not a new song but I can't remember what uth was.

Yep, that's been a canned Sting line at just about every show. I really wish he'd at least mix up the patter a little bit...
