After mentioning it a few days ago, I kept thinking about "Lucifer." Last night I figured out the guitar parts for one section (I'm pretty sure it's doubled with auto-harp). I might have the rhythm wrong in the second half though. I figured out an-other part too, but I'm not sure what instrument it's actually played on. I used electric piano, but the APP website lists only "synths," so…?
In looking that up, I've discovered that the rhythm in that part spells out EVE - the name of the album - in Morse code. I'd been suspicious of something like that.
As a basis for my recording I used the early rough mix that's a bonus track on the CD re-issue, so there might be slight differences between this and the final version.
