This paper studies the lyrics of songs performed in the 2008 Olympics in which identities and ideologies are the primary meanings conveyed by code-switching. In some songs, English comes to symbolize a global identity which includes the Chinese and other nationalities. In others, English comes to represent the West whereas Chinese comes to represent the East, and crossing (Rampton 1995, etc.) between East and West is accomplished quintessentially by performance. Crossing also takes place when there is no code-switching. Notwithstanding the utopian ideals portrayed in these songs which are fitting for the Olympic games, linguistic imperialism and hegemony can be detected in the language ideologies underlying these texts; the most salient ones being that English stands for the West and the world, and Putonghua stands for the East. Diversity (linguistic, cultural, ethnic, etc.) under the East and the West is largely suppressed and under-represented.
