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
