I had the movie portion of this on a tape, I plugged the VCR into the stereo and recorded that chain gang part, and the short jazzy horseriding sequence after it in the movie. Never knew who it was. Great film sequence.
I had to stop Posse in the middle just now (amazed I never saw it before) to look up this haunting song, so perfect for the scene. Many thanks, S.Y. Peace TV! Do you, or does anyone here, know whether the Neville Brothers ever recorded or performed the song outside the movie sound track?
