Well, I was going to offer the chords I use for "BD", but I don't suppose that anyone is interested in that sort of thing... not any more, anyway.
Having worked in a State Institution for the Developmentally Disabled (formerly known as "Mentally Retarded") for about 12 1/2 years, I am no stranger to the sort of literal environment that seems to be figuratively developing here - but that is not to imply that I have ever come to enjoy it.
So "ta-ta", "Gentlemen"; we are off to the light of another campfire.
