Cover art for Knee Deep lyrics by Job For A Cowboy

I think it’s about a man that was an alcoholic or a drug addict and he was dying, but he was so consumed by the alcohol and drugs that he couldn’t think straight and it ruined his life. When he died he left it all with his son. But his fixations, as they say, would never end, and he still thought as if he was still on the drugs or alcohol, when he came back to life as a “walking corpse,” or zombie. When they say “he will remain a walking corpse his legs will move forward” they mean he’s being controlled by the drug and alcohol induced thoughts and since he couldn’t think straight he killed his son.
