@ biscuithead: I have experienced something similar twice; once with a friend of a friend; and once with a friend.
They just stood there and looked toward the stage. NO emptions at ALL! WTF? Why not just stay home?
I mean, I´m head banging and enjoying the SHIT out of myself, and these gus just stand there.
I asked the friend of a friend what he thought of the show afterwards, and he just said it was ok.
My friend said he liked it, but just didn´t show it.
I must take a step backward and share a story that lends to the other side...
My father-in-law is a HUGE Moody Blues fan. He has gone to well over 250 shows since his first in Denver, December 1970. He plans European vacations around their tour dates.
He is a Big Fan. He invites me to a Red Rocks show a couple of years ago... I'm not that big of a fan of the Moody Blues, but I say sure... maybe I'm missing something about them, and maybe their live show will speak to me...
The show was fine, and I grooved a little... but more importantly, HE (My Moody-Blue-worshipping-father-in-Law) just sat there! He was not moving, snapping his fingers or anything... He did sing along on a few songs, and he did close his eyes...
So, here this guy is, seen the Moody Blues all over the world, and he seems very non-plussed by the event.
I ask him afterword, on the drive home, "how did it compare to the other shows you've seen"?
His reply: "It was pretty good".
Conclusion: I don't know what goes on inside other people. Personality, insecurity, blah, blah... We all have our own experiences, and mine is not better, or more whole, than his, or any ones. I enjoy my music outwardly, others can do it their own style. I will work on not judging my wife for not dancing.
Thanks to everyone for holding up the mirror.
