I've got a song in my head

And I'm worrying about it.

It's Tom Paxton's "Lyndon Johnson Told the Nation"

And my brain has replaced "Lyndon Johnson" with "Barack Obama" and "We're sending fifty thousand more, To help save Viet nam from Viet namese." with "We're sending forty thousand more, To help save Afganistan from the Afganis"

So, like I said...worried.
