Folks, the angular momentum is NOT conserved -- at least in the beginning
and I don't see why it should be currently.  There is no requirement that it
need be!  There is an external torque on the Moon!

What am I missing?????  I guess I just can't follow what you are talking
about.  Somebody help this poor senile person out.
