“I had been listening to an album called Sonic Seasoning by Walter Carlos, who’s now Wendy Carlos, and it gave me the idea for this sound effect that came from outer space. It came towards you and then bang! – the band started charging. At first, there’s this wonderful musical chaos, and then we have the guitar riff.

“The idea of the chant was key to the song. [Sings] ‘A seasoned witch could call you from the depths of your disgrace/ And rearrange-da-dada-dada-dada-da-da-daa.’ It’s a rhythmic thing. I worked that out with Steve.

“The band started playing, and I said, ‘Guys, maybe you should be doing something more syncopated instead of a straight-on beat.’ So while Bill and Chris worked on a drum and bass thing, I looked at Rick and said, ‘OK, how fast can you play?’ And, of course, he could play very fast. The whole idea was to make it musically entertaining even before we put the voices on.

“For lyrics, I did a rough sketch of the whole piece, but as the sections came together, that’s when I rewrote the words. It took about three or four revisions till everything was there. It’s all metaphors. Simply put, ‘A seasoned witch could call you from the depths of your disgrace’ – that means your higher self will eventually bring you out of your dark world.”
