Lyric discussion by Hatz 

Cover art for Dark Star lyrics by Crosby, Stills, Nash & Young

It's about Still's looking at a relationship with a Dark-Skinned woman and the taboo that was in the South. Stills is a native of Louisiana and knows the prejudices of society. To be white and with a black intimately would be the biggest taboo of his upbringing but he thinks more of her than the taboo.
