Maxwell's Silver Hammer is a song from The Beatles' last recorded album, Abbey Road. It's also the song that made the other three members of the band wish they had a silver hammer to bang bang over Paul McCartney's head.
The song, released in 1969 on The Beatles last recorded album, Abbey Road is about a medical student named Maxwell Edison who decides to murder a few people with a silver hammer. Despite the dark subject matter it's a very upbeat song. It just comes to show that at some point in the `60s, Paul McCartney lost his mind. It may have happened somewhere in-between dumping Jane Asher and writing Wild Honey Pie.
The other three members of The Beatles: John Lennon, George Harrison, and Ringo Starr hated the song with a passion. Why? Well, for various reasons. Lennon was getting tired of McCartney's silly songs. This was, after all, the man who contributed Come Together and I Want You (She's So Heavy) on the album. Harrison was notorious for hating everything. And, Ringo was just a follower. So, they all ganged up on him and stopped the song from becoming a single. Harrison's Something and Lennon's Come Together were chosen instead. Both made it to #1.
Maxwell's Silver Hammer, on the other hand, is now just a song that McCartney listens to alone on his mansion every Halloween.
