Apparently this was floating around the internet a while ago: a YouTube/youku video featuring Hong Kong mega popstar Andy Lau entitled 德华成都演唱会怒打保安救歌迷 (Andy Lau attacks security at a Chengdu concert to save his fan). The video shows:
The fan clambering towards the stage with a bouquet of flowers.
The fan shakes Andy Lau’s hand, in the middle of a song.
The fan gets dragged off and mobbed by a group of security guards.
Andy Lau sees this, stops his song and jumps heroically off-stage towards the mob.
I’m particularly impressed by the fact that Mr Lau apparently managed to continue singing throughout the incident. Now that shows real star quality.
^^ ROTF!
