No...I never have...o_o;
I always watch concerts late at night. I was watching Ayumi's 2000 Concert B and I fell asleep...
I do run around and throw fists at the air with Mocchi during the Many Pieces 2003 tour because she's much more lively...
My other concerts, Mika's LOVE FINAL and DAI's DEEP FOREST are really just for sitting and watching. ELT concerts are so energetic!
