Lexx

Why didn't anybody ever point out that the fourth season of Lexx is a lot better than the third one was? I've had S4 around for years, but never bothered to watch it. I started in on it this weekend while stuck in bed with a really bad cold (39°C/103°F fever bad), am now up to episode six ("The Rock") and so far it's damn near brilliant. The people who made this thing didn't have a single neuron screwed on straight.

ETA: By the way, does anyone here know if the folk music version of the fight song of the Brunnen-G from the pub scenes in "The Rock" is available on a soundtrack CD or something?
