Thanks for posting this, it's a good doc.
Can anyone ID the music that starts at 5:40 and finishes at 6:19?
It's guitar-driven instrumental rock, but the narrator talks over most of it.
The music is clearest when the narrator isn't talking at 5:47-5:53, and 6:17-6:19 - but neither segment is long enough for Shazam :-(
I posted the same question as a youtube comment but no answer...
