The Beatles’ 1965 song “Yesterday” is a delicate ballad of heartbreak that has since become one of the most covered songs ever. Paul McCartney famously dreamed its melody and recorded it solo with a string quartet, marking a departure from the band’s rock sound. Its poignant reflection on lost love resonated widely – topping the charts in the US – and demonstrated a new maturity in pop music. Decades later, “Yesterday” remains a timeless highlight of the Beatles’ catalog, admired for its simplicity and emotional depth.
