I walked out of a much anticipated Roger Waters / Pink Floyd concert in Shanghai in 2006. He showed his commie blood and it made mine boil - flying a giant inflatable pig covered in blood with George Bush printed on its ass. I stood up, flipped him off with both hands and walked out.
Took a cab to Xin Tian Di and had a nice Italian dinner at Va Bene - great selection of Pinot Grigios.
Good choice. :)
