I've seen them quite a few times on the current tour. All the shows have been different in some aspect. I don't think I've ever seen them looking irritated with each other on stage. There were definitely shows when they were downright giddy and obviously having a blast.
I saw them 4 times on this recent tour. Each show was different in many ways... Playlist, Attire, Little subtleties. Sting sang w/ Elvis Costello on one of his songs... sometimes. I enjoyed all of the shows. I didn't see any problems w/ Sting and Andy. Andy did seem to struggle at times, but keep in mind he's 65 y/o. He nailed it perfect on some of the shows though.
ANDY IS 65! Yikes.......Where does time go-Hey, I don't know about you guys...but, I'm still 18! hahaha.....I did see the concert in HI and I thought it was a little scattered-sloppy. I felt they didn't cover some of the MAIN SONGS I was excited about seeing them play...and it seemed RUSHED. :( And, supposedly that was the LAST concert. And, then all of a sudden here goes another kick off tour here in the mainland-HAHA. I guess that's marketing, though-ANYWAY. All in all, I was still psyched to see them live! :)
