I was doing all the music at that time, so I just kept composing, kept composing because I loved to compose. Get up in the middle of the night. I remember when I did "Satan's Fall" that was maybe within a week or two. Every night until 3AM, I was sitting with my guitar and then taking, finding the next part. Back to bed and up again. That was cool.
