Maybe too personal but looking and listening to Glenn's lyrics and Twitter comments; has he been on a 12 step program? He refers to his 'Higher Power' quite a lot. I have been encouraged by the lyrics many times.
But on an interview Glenn says that he believes in past lives, I think. So don't know what to make of that.
It would be great to read an autobiography [as most members of this forum would be interested]. Its always heartening to hear of people who have been through the gutter and darkest places of the soul and come out changed fundamentally; how they view themselves and how our higher power [God] views us. They say 'never talk about religion and politics' but I bring it up because Glenn speaks so much about it directly and indirectly in lyrics and it is very interesting.
