Checked to be certain and, yes, 'Do You Know Where You're Going To' was the theme song. Always enjoyed the recordings of Diana Ross, but this was certainly not a favorite. When she's hot, she's hot. When she's not, she's not.
Enjoyed her movie 'Lady Sings the Blues' far more than her efforts in 'Mahogany'.
IMHO it rates on the same level as
Love Child,another miscalculation.
I have always interpreted
Love Child being the story of a girl, probably from a "petty bourgeois" background, who grows up in Communist China during the Mao Tse-tung era and is treated as a "class enemy" by the Communists.
