What is the meaning of the song "Highwayman"?

Sung by both Glen Campbell and the Highwaymen. The lyrics seem quite weird...does the song really mean anything?

the person 'narrating' the song (the 'highwayman') is recounting his various deaths and reincarnations...

that's what makes me the version by johnny cash, willie nelson, kris kristofferson and waylon jennings so spooky and powerful...cuz each 'life story' is being performed by a different artist...
