Battle of the Beards

[The Stranger]

I was watching the music video for Johnny Cash's "God's Gonna Cut You Down." and I couldn't decide who the guy was at the beginning and at the end. Then I realized how many country/blues/southern rock guys have dark long hair and beards. I figured out who the guy in the video was. Who else here can list who these people are, and which two appeared in the video?
















edit: one didn't show up the first time + new video link
