You are entering the Aquarian Zone of  The American Tribal Love-Rock Musical  H A I R

WOOF:  Earthians unite!

To the TRIBERS:  Bare your soles to bare your soul...

There is air in HAIR, both the song and the title.  Aquarius is an air sign.

HAIR (subtitled The American Tribal Love-Rock Musical) was created by the three gentlemen pictured here, Gerome Ragni, Galt MacDermot and James Rado.   Jerry and Jim, from Pittsburgh, Pa. and Washington, D.C, respectively, at the start of their New York acting careers,  became friends in 1964 after being cast together in an off-Broadway musical HANG DOWN YOUR HEAD AND DIE (whose theme was anti-capital punishment).
