Actual inbreeding might explain Stevens' current attempt to become a right-wing singer/songwriter, but with even less of a sense of humor than he had before.
I know he took his attempt to be a "serious" country singer really hard when sales tanked, but blaming Obama for that is... about as rational as most of that kind of thing, so I guess it makes sense.
I first heard this song on an old 78 rpm record my mom had, except it was a woman, and all the genders were flipped. At the time, I thought it was one of the funniest things I'd ever heard.
