I was an avid follower BBC Apollo coverage, remember "Also Sprach Zarathustra" a bit of an obvious choice, but worked well nevertheless.
Burke and Moore Michelmore and their guests taught me much of the NASA jargon and acronyms and made me the playground expert, but there were a few things I picked up on that were not explained, one such thing I first heard, I think on Apollo 8, was the expression "All Balls".
I kind of guessed it was the initial zero display on the DISKEY, I recently found the definitive answer, and I was at least in the right ball-park!
