Yes, the seated/standing thing is a factor, as well as the country. I'm sure GA shows in Spain are MUCH more energetic than in Germany
Oh well, MK is not Bruce Springsteen (where the heck does HE get all the energy from? I think he's the same age as MK...), and as long as the mood, the quality and the music is right...
I'd prefer MK not to play seated again, though
