Green Green Grass of Tunnel

Down from my ceiling Drips great noise. It drips on my head through a hole in the roof Behind these two hills here There's a pool And when I'm swimming In through a tunnel I shut my eyes Inside their cabin I make sounds In through the tubes I send this noise. Behind these two hills here Fall asleep And when i float in Green grass of tunnel It flows back Down from my ceiling Drips great noise It drips on my head through a hole in the roof Behind these two hills here There's a pool And when i'm swimming In through a tunnel I shut my eyes
