Big Train

There's a big train coming I know it's coming along There's a slow train moving Rolling down that old line It's been a long time coming A long time coming along We're all riding on this freight train It's made of rocks and dirt and water We've got lots of bricks and stuff But we ain't got no mortar The driver's sleeping at the wheel Or maybe there just ain't no driver When people get to moving We just got to get on board We're all riding though this emptiness You just got to trust your neighbour
