• When it was first performed, in the United States and then Britain, the musical Hair was extremely controversial; its overt profanity was probably the least shocking of its features for the establishment. The passage of time has largely masked this.
  
  Like the rest of the songs in the show, the title song has lyrics by James Rado and Gerome Ragni, music by Galt MacDermot. The song is basically an ode to long hair, at a time when men had just begun to wear it long again, during the hippie era, which is what this musical is about. It is performed by Claude, Berger, and the Tribe. "Hair" is not of course to be confused with the Lady Gaga song; she was not born until nearly 20 years after it was first produced. >>>
