Could someone please help research the genesis [etymology/etiology] of the following Black Liberation Theology chant: ...half-notes scattered without rhythm / no tune distraught laughter fallin' over a black girl's shoulder it's funny / it's hysterical the melody-less-ness of her dance don't tell a soul she's dancing on beer cans and shingles... somebody / anybody sing a black girl's song bring her out to know herself to know you but sing her rhythms carin' / struggle / hard times sing her song of life... I found god in myself and I loved her / I loved her fiercely I'm getting hits...
