The narrator character of most They Might Be Giants songs sees the topic of the song through a funhouse mirror. The topic of changing the world is no exception. "Purple Toupee" portrayed an out-of-touch older man who wants to be seen as influential on the world stage, but barely understands events of the mid-twentieth century.
"Celebration" is the spiritual successor of those songs, modernized for the attitude of the internet era. The connection will become clear to you if you listen to "Celebration" after watching the Portlandia sketch "Change The World One Party At A Time", skewering the tendency for youth activism to take the form of a dance rave in which to get really f****d up.
