Lyric discussion by TMiller68 

Nuclear war survivor talking to someone on Ham radio. not sure if anyone else is alive in that part of the US. He says "he the king of the world as far as I know"...

My take

@TMiller68 Yes. I never bothered to try to find out what that line about marigolds as about until today. I did a bit of googling and found - webmd.com/vitamins/ai/ingredientmono-235/calendula

Calendula is applied to the skin to reduce pain and swelling (It is thought that the chemicals in calendula help new tissue grow in wounds and decrease swelling in the mouth and throat.) Don’t confuse calendula with ornamental marigolds of the Tagets genus, which are commonly grown in vegetable gardens.
