Maybe a lot of the problems arise because he is trying to "conquer" the world all in one go too. I mean I have never known an artist to do this before to such the extent Mika does. He is in a different country from one day to the next. I don't think he knows how to take things slowly! Most bands/artists will tour maybe once a year, usually to tie in with the promotion of a new album, but Mika seems to be doing it constantly - as soon as one tour finishes another starts in another country, with extra shows and festivals dotted in all over the place... and then back round again!
It is easy to see how problems are going to arise, but it certainly isn't fair on the fans when things go wrong which they inevitably will with a schedule like this. But on the flip side of the coin - as this forum shows he already has fans all over the world - all of whom want to see him play in their country or part of the world, so can there really be a solution to this?
