Xiangsheng has connections with the vaudeville Double act that developed in approximately the same era. Some Westerners have studied the art of Xiangsheng.[3][4] One Canadian student of Xiangsheng, Mark Rowswell, who uses the stage name of Dashan, has said that the closest English equivalent is "Who's on First?", a sketch by Abbott and Costello.[5] However, many acts in vaudeville and radio double acts, as well as the screen comedy dialog that evolved from them, are similar to Xiangsheng in their formula.
