Brilliant find! Love it, made my evening.
I have heard this recording before but never heard it (or seen it) in this format, truly awesome stuff and to get an idea and comprehend how the crew and mission control communicate is stunning IMO. Great to move straight to the points of interest. A chap named "Rog" is very popular too.
When asked (30 something years ago) at primary school what I wanted to be as a grown up I simply said "Neil Armsrong". LEG END's, the lot of them.
EDIT: Hitting the invisible "Thank You" button.
