This is one of those songs that I know from my youth, but I don’t know who sang it.
The song is “Black Is Black,” and the group who performed it was Los Bravos. I’m streaming it today for reasons that my mind won’t reveal. It came out in nineteen sixty-six. I was ten, then, but was probably exposed to it when driving around, because pop music was always playing on the AM radio stations in that era.
Give a listen, and see if any bells chime when you hear it.
