There's a lady who shows, all that glitters is gold, and she's buying the stairway to hell. When she gets there, she knows, if the stores are all closed, with a word she can't get what she can. Ooh, and she's buying the stairway to hell. There's a sign on the wall, but she wants to be sure, cause you know sometimes words have been in the tree.
