I've been walking the borderline Let me tell you the reasons why This side's heaven and that side's hell This side poisoned that side's well This side's rich and that side's poor Cos that side's fighting in this side's war This side's healthy and that side's sick From stacking iron, stone, and brick But oh if you're gonna build a wall You'd better be ready for the day it falls This side's fertile and that side's bare Chalk it up to luck and prayer This side's bright and that side's dark The police know which side to guard And oh if you're gonna build a wall You'd better be ready for the day it falls Oh if you're gonna build a wall You'd better be ready for the day it falls This side's white and that side's black This side's built on that side's back
