"Yer Blues" finds John Lennon wrestling with profound feelings of despair, even suicidal thoughts, while trying to write a blues song. It’s a half-satirical, half-earnest commentary on the British blues boom of 1968, where Lennon parodies English blues imitators while acknowledging his own insecurity about whether he, a white man, could genuinely sing the blues. He alludes to other blues artists and even Bob Dylan, creating a song that playfully questions the meaning behind bluesy poetics. This song plays like a raw, self-aware exploration of artistic identity and emotional turmoil, wrapped in a blues framework.
