"Are You Hung Up?" is a short montage of dialogue and musique concrète, lasting 1 minute and 24 seconds. It includes stuttering hippie vocals by Eric Clapton, "Uh, out of sight. Are, are you hung up?", engineer Gary Kellgren whispering about Frank Zappa's mighty, omniscient presence in the control room, a brief guitar lick and Jimmy Carl Black saying "Hi, boys and girls, I'm Jimmy Carl Black and I'm the Indian of the group" and then laughing. Black's statement, a catchphrase used frequently by him in concert, is also used on the song "Concentration Moon" and resurfaces on later recordings by the Mothers of Invention [clarification needed].
