Do you really think that adding two new songs to the setlist would have jammed the buzz on their reunion tour?
When "Don't stand '86" was released as a single, it was quite a flop... But the "Every breath you take" compilation was a huge hit. I cannot think 2 songs in the 2007 setlist would have changed that much the reunion tour, which is mostly based on greatest hits.
I'm not sure there will be anything after this tour, except maybe an unplugged album & a live album (including 1 or 2 DVDs)... well, that's not too bad for a band who disbanded 23 years ago!
But I don't really care, they're back for 2007 (and 2008?) and I want to enjoy the present time.
