Why* you'd ask if you saw me now,
My head slung low and shoulders down.
You used to be so big and strong,
Baby tell me what went wrong.
Why won't you tell me what went wrong
I used to be a tower, but now I am no more.
I used to wield such power, likes never seen before.
I used to be a castle, till one crept in 'guised silly and aloof.
And razed my lands around me while I fiddled on the roof.
My first castle sank into the swamp. My second castle fell over and sank into the swamp. My third castle burned down, fell over, and sank into the swamp. But the fourth castle stayed up.
