I'm listening to the old NPR All Things Considered theme from between 1983 to 1995 (https://youtu.be/u5MKiTdWo4E) and have always heard Morse code. I can't figure out what it's saying. I hear either - dit-dit / dit-dah-dit-dah-dit or dit-dit / dah-dah-dit-dah-dit. What is it actually saying and is it something composer B.J. Liederman inserted as something for insiders?
