van der graaf generator - a plague of lighthouse keepers: s.h.m. lyrics

'unreal, unreal' ghost helmsmen scream
and fall in through the sky,
not breaking through my seagull shrieks...
no breaks until i die:
the spectres scratch on window-slits -
hollowed faces and mindless grins
only intent on destroying what they've lost.

i crawl the wall till steepness ends
in the vertical fall;
my pain has sailed into the sea:
no joking hopes at dawn.
white bone shine in the iron-jaw mask
lost mastheads pierce the freezing dark
and parallel my isolated tower...
no paraffin for the flame
no harbour left to gain.
