OK, I've fixed it, but I'm not sure why. More about that later.

These permissions are identical for the Pi 2 running the SD Card that worked
in August and the Pi 3 running the latest Raspbian. (Except, this gave me the
clue, because the directory names were different on the two devices).

Why do I need to switch to root ? The command below is prefixed with sudo.

The user is root. Is that normal?

Well the command put me into the root home directory, so I wasn't sure what
this was doing.
=== The solution ===
When I spotted that the the directory names were different on the two devices,
I tried surfing to the correct one on the Pi 2; this worked (I had forgotten
that I changed them when I moved to the Pi. I then changed the directory
names on the Pi 3 to match the Pi 2 and everything worked.
My recollection is that I only changed those names on the Pi (compared to the
version on my server), to make typing easier, but clearly having the Directory
names as Audio_Guide and Kiddies_Quiz instead of Guide and Quiz was what was
needed.
Why would that be?
