I saw the original Sydney production in 1970. First ever full nudity on an Australian stage. This 12 y/o was not so much impressed by the nudity as the lines-
Claude (holding up a poster of David Bowie)- Wow, I'm not a homosexual or anything but I'd love to sleep with that guy!

She asks me why, I'm just a hairy guy
I'm hairy noon and night, hair that's a fright
I'm hairy high and low, don't ask me why, don't know
It's not for lack of bread, like the grateful Dead, darlin'

Give me a head with hair, long beautiful hair
Shining, gleaming, streaming, flaxen, waxen
Give me down to there, hair, shoulder length or longer
Here baby, there, momma, everywhere, daddy, daddy

Hair, flow it, show it
Long as God can grow, my hair

Let it fly in the breeze and get caught in the trees
Give a home to the fleas, in my hair
A home for fleas, a hive for the buzzing bees
A nest for birds, there ain't no words
For the beauty, splendor, the wonder of my hair

Flow it, show it
Long as God can grow, my hair

I want long, straight, curly, fuzzy, snaggy, shaggy, ratty, matty
Oily, greasy, fleecy, shining, gleaming, streaming, flaxen, waxen
Knotted, polka dotted, twisted, beaded, braided
Powered, flowered and confettied
Bangled, tangled, spangled and spahettied

Oh say, can you see my eyes if you can
Then my hair's too short
Down with here, down to there
Down till there, down to where it's stuck by itself

They'll be ga-ga at the go-go, when they see me in my toga
My toga made of blond, brilliantined, biblical hair
My hair like Jesus wore it, Hallelujah I adore it
Hallelujah Mary loved her son, why don't my mother love me?

Hair, flow it, show it
Long as God can grow
My hair, flow it, show it
Long as God can grow
My hair, flow it, show it
Long as God can grow
My hair
