Well, people the problem with Stratovarius songs is that they are always maybe one of the most difficult to sing live and that high notes are impossible. TK have amazing performances, search for Raunmanmari in youtube (in my youtube account I have the full concert):

Of course, he has lost a lot of range these past years (this has been discussed in the official forums 100000 times), but in studio he sounds perfect. In this tour he has been infected with a bacteria, a food poisoning.... and he stills not singing like he used to, but take a look at this little video of Infernal Maze, I think is great:

And the band is now instrumentally fantastic live, sounds amazing live.
And the last concertwith TT was in Madrid, I made a topic about it in Stratoforum:

Now I remember that Jens talked about it in the topic.
