John Lennon & Yoko Ono
Back in 1972, lovers and tabloid magents John Lennon and Yoko Ono released the single "Woman is the N***er of the World," much to the shock of fans worldwide. Here's a sample of the lyrics: "Woman is the n***er of the world, yes, she is/If you don't believe me take a look at the one you're with/Woman is the slave of the slaves."
Lennon's intention was to describe the subservience of women, who were at the height of their struggle for equality. During an appearance on The Dick Cavett Show, the former Beatles member attributed the song's inspiration to Irish revolutionary James Connolly, who once said "female is the slave of the slaves."
Despite Lennon's intellectual explanation, the single was pulled from shelves in Britain, and, according to Billboard, was the lowest ranking single Lennon released in the entirety of his career.
