Yeaaahhh, so true, especially the amount of professionalism it takes. This is a little off-tangent from your point, but I read someone's comment on how JE probably chose very brightly coloured, sequin'ed costumes for a practical reason - so it's easier for the audience to see the boys when they're moving around the concert hall. And it hit me that, oh yeah... they may have vomited rainbows on the outfits, but they're doing it for fans.

It just makes me respect them so much more. *__*
