I just couldn't do it today. I'm still keeping it to three voices, but... well, hang out until the end of the song.
I think the verdict is: three's good to try for, and some songs will reveal to you that their arrangement and/or orchestration requires something else. So, this one goes down as an exciting idea that would need to be re-worked to turn it into a recording or performance that I'd be most proud of.
But dang. I like parts of this.
