Sorry, Lionel. These optimistic people are wrong. It is about drugs. "Won't you take a ride on the flying spoon" gives it away. You heat powdered drugs and water in a spoon to liquify the drug, usually heroin, to make it injectable. If you live out in the country and want to get high, you would probably make a trip to a big city to buy it, such as Chicago or East Saint Louis ("Just got back from Illinois"), and would lock the front door so as not to be disturbed while you sat on the back porch. And yes, there will be happy creatures, so long as you stay happy, too.

It is a very interesting and believable tableau from the life of a rural doper. It's one of my favorite songs, and children will enjoy it very much, so long as they don't know what's going on.
