This is a song about dying and the soul's journey from the body to the outer reaches of the galaxy.  This has been documented by some who have died and come back to tell about it, I hope to experience this version of the tunnel ride when I go.   Some of the change up parts towards the end are things I wrote when I was 15 and just playing ideas by ear, I thought this would be a good song to use them in.  The leads are really For The Love Of God inspired, that was one of the first songs I learned before I knew any scales or anything.

I guess you could count the x4s for the lack of tab here, if you want more, just ask.
