This song, though it gives no specific year, is clearly referring to a pre-adolescent:

When I was a lad of three-foot-three / Certain questions occurred to me,
So I asked me father quite seriously / To tell me the story 'bout the bird and bee.
He stammered and he stuttered pathetically / And this is what he said to me.

He said, "The woman piaba and the man piaba
and the Ton Ton call baka lemon grass,
The lily root, gully root, belly root uhmm,
And the famous grandy scratch scratch."

[and one more line, starting the next verse: It was clear as mud but it covered the ground]

-- Man Piaba by Harry Belafonte
