I'm glad someone finally brought the numbers forward, because I'm really tired with all the moaners.
And just a couple of facts: For a musician it's normally not boring to play the same song over and over again. The more you know the song, the more you can improve, improvise and make it your part your own. I think it's the same for acting, for instance. And classical music. You rehearse hundreds of times and perform lots of times afterwords. You don't vary the play just because some spectators choose to watch multiple shows.
About clothing: I absolutely agree that MK and his band mates could have needed some advice when it comes to stage wear. But it's completely normal for an artist to wear similar (or exactly the same) stage clothes throughout a tour. If you check out pictures from Springsteens tour a couple of years ago, he wore the same black shirt, dark blue jeans, black belt and black boots throughout the whole tour. I saw him three times during that tour, and he told the same jokes every time. But who cares?!!! The shows were great, mistakes and all.
