This is a song by English rock band the Beatles, released in 1968 on their self-titled double album commonly known as the White Album. Musically it is a rock-and-roll pastiche that blends driving 1950s-style guitar and piano with surf- and soul-influenced rhythms and harmonised vocals, serving as an energetic opening that reflected the band's engagement with American popular music and a playful commentary within their late-1960s work.
