Duke Ellington & His Orchestra - Don't You Know I Care (or Don't You Care to Know) (take 1) lyrics

Don't you know I care Or don't you care to know? If you know I care How could you hurt me so? Darling, you are part Of every breath I take Will you break my heart Or give my heart a break? I can't figure out what love's all about And where I fit into your scheme Am I wasting time? Please tell me 'Cause I'm down to my last dream Won't you please be fair? Love me or let me go Don't you know I care Or don't you care to know?
