I do know the second dates from 1993 when I was in Cupertino and newly come to the US.
in the twilight of the year
when all is night;
venture forth all those
who flee the light
to dance, to prance and merry-make
o'er all the world 'fore dawn should break
to win, to woo, to fright, to thrall
and mysteries hid reveal to all
to scale the furthest, safest tower
and steal within most virtuous bower
the wary, cautious, shy to tempt
and rusting, dusting sleep prevent
and tear away from righteous "Nay"
and whisper soft, "come on, let's play!"
The land was still and quiet
And a full moon
Looked down from an untroubled sky
A strange Presence -
Or perhaps Absence
Was sensed, was felt,
Yet unseen when sought.
An ancient, ancient memory
From the very bones of my Race
For this was the Eve of
The Eve of All Hallows
And Strangeness walked the Land.
