가사
Joan was quizzical, studied petaphysical Science in the home Late nights all alone with a test-tube Oh-oh-oh-oh... Maxwell Edison majoring in medicine Calls her on the phone "Can I take you out to the pictures Joa-oa-oa-oan?"
But as she's getting ready to go A knock comes on the door...
Bang, bang, Maxwell's silver hammer Came down upon her head Bang, bang, Maxwell's silver hammer Made sure that she was dead
Back in school again Maxwell plays the fool again Teacher gets annoyed Wishing to avoid an unpleasant sce-e-e-ene She tells Max to stay when the class has gone away So he waits behind Writing 50 times "I must not be so-o-o-o-o..." But when she turns her back on the boy He creeps up from behind
Bang, bang, Maxwell's silver hammer Came down upon her head Bang, bang, Maxwell's silver hammer Made sure that she was dead
P.C. Thirty-one said "we caught a dirty one" Maxwell stands alone Painting testimonial pictures oh-oh-oh-oh Rose and Valerie screaming from the gallery Say he must go free (Maxwell must go free) The judge does not agree and he tells them so-o-o But as the words are leaving his lips A noise comes from behind
Bang, bang, Maxwell's silver hammer Came down upon his head Bang, Bang, Maxwell's silver hammer Made sure that he was dead Oh-oh-oh-oh
Silver Hammer Man!
