Okay, the lead singer is a man that has a rich baritone, and sounds like a black soul singer (maybe Ray Charles?). He’s backed up by a chorus which chimes in periodically to accent the lyrics. Below is a garbled version of what I can remember, with parts where the chorus is singing bolded:
Tell me why we hold on with tears in our eyes
Tell me why I break down when I tell you goodbye
Tell me why I can’t see . . . . .[something, something]
I’ve tried Googling this, but nothing popped up that seemed to match.
