This is a rock song that I heard on the radio when I was a young teenager during the seventies. They played it a few times — so it might have been some sort of a minor hit. The song was was certainly _somewhat_ unusual in that it was a kind of hard rock/art rock piece with a female singer. I also remember a short section of the song where the sound of bullets being fired and whizzing through the air. The song might have had some kind of Wild West theme. From time to time, I have been thinking of the song ever since. It would be greatly appreciated if someone could let me know a good guess on which song it was.
