Being used to scientific terminology and theory it was always natural for me to push this stuff into songs.
I continue to believe, contrary to the given wisdom, that it's more interesting to have an album - or, indeed, an individual song - which has variety rather than homogeneity.
Marc Almond has done a couple of covers, a few people in Europa have done them. I own all the publishing. It's never really been addressed, as I haven't had the time to go out and tout the songs.
