That Joan Armatrading song reminded me of a time I saw her on a double bill with Graham Nash. Much of the audience seemed to fall into three broad categories: old hippies, lesbians, and middle-aged African American couples. I was pretty sure I knew which act each group was mostly there for.
(I didn't quite fit into any of those categories, oddly enough. I went mostly to hear JA.)
There's a short motif in the Lord of the Rings soundtracks that is such a deliciously blatant steal from that part of the Rite of Spring that I can't even be mad. But as Stravinsky himself has often been misquoted as saying, "Good artists copy; great artists steal."
