Ok, there’s a couple on that list that I think are pretty serious thinking guys. Dylan. Maybe Bono, maybe not. Townsend, maybe. Garcia might be interesting.
Lennon, no. Commie. Imagine no possessions. Not a deep thinker. I liked Harrison better.
I think that there are a few others that would be pretty significant thinkers in the world of Rock. Bowie, as you mentioned. Roger Waters comes to mind. Don’t overlook Eric Clapton.
Billy Joel too.
