Lyric discussion by harlan7821 

Cover art for Who Are You Now? lyrics by Olivia Newton-John

2 meanings; one the who is someone that has Alzheimer’s disease that brings so many changes as the disease progresses and the original person’s personality becomes a distant memory and now is more combative and scared. 2nd meaning is a person struggling with depression, bipolar disorder or borderline personality disorder. The song fits perfectly both scenarios. I suspect the lyrics original intent was the evolving relationship between married partners. Either way it’s such a beautiful sweet song and melody from Olivia who could always find brightness even in a dark world.
