McCartney said in 1994 that it merely epitomises the downfalls of life:
"Maxwell's Silver Hammer" is my analogy for when something goes wrong out of the blue, as it so often does, as I was beginning to find out at that time in my life. I wanted something symbolic of that, so to me it was some fictitious character called Maxwell with a silver hammer. I don't know why it was silver, it just sounded better than Maxwell's hammer. It was needed for scanning. We still use that expression now when something unexpected happens."
McCartney referred to the song when talking about his 2005 album Chaos and Creation in the Backyard:
"In the past I may have written tongue-in-cheek, like 'Maxwell's Silver Hammer', and dealt with matters of fate in a kind of comical, parody manner. It just so happens in this batch of songs I would look at these subjects and thought it was good for writing. If it's good enough to take to your psychiatrist, it's good enough to make a song of."
Lyrics and video..
Joan was quizzical; Studies pataphysical
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.
Clang! Clang! 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 fifty times "I must not be
So, 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.
Clang! Clang! 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, 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.
Clang! Clang! Maxwell's silver hammer
Made sure that he was dead.
Whoa, oh, oh Silver hammer,
Maxwell's Silver Hammer flash video
