On June 29, 2011, the Chongqing Municipal government held a giant “Red Song Gala” at the Olympic Sports Center in celebration of the Chinese Communist Party’s 90th anniversary. It is claimed that 100,000 people at the stadium sang simultaneously along with the main singers, turning the sports center into a sea of song. Chongqing’s CCP chief Bo Xilai, along with former U.S. Secretary of State Kissinger and other senior Party and military officials, attended the gala. The gala started by singing the song “Follow the Communist Party” and reciting “The Communist Manifesto,” followed by other “classic red songs.”
