I started off with this Rush like riff, so thought "OK" and went in that direction", but I had this old riff as well, that had travelled with me across a millennium from a time long ago. So in the middle it is a bit like Donna Summer meets Blake's Seven. So I thought, "well here we are with a pop diva and an interstellar fugitive, that's an interesting nut to crack, just for good measure I'll throw in an old salty sea shanty as well." Either I cracked the nut, or it cracked me! Enjoy your Rush'ian Walnut salad!
