On January 1, 1965, The Beatles performed "I Should Have Known Better" during a live show in Blackpool. At this point in their career, the band had already released their album "Beatles for Sale" in December 1964, showcasing their growth as songwriters and musicians. The live performance captured the band's high energy and the excitement that surrounded them during the height of Beatlemania. An interesting fact about this era is that their musical style was evolving rapidly, transitioning from pop hits to more experimental sounds that would culminate in their later works, such as "Rubber Soul," which was released just a few months later in December 1965. This specific performance also illustrates the band's significant popularity and their commitment to live shows, as they captivated audiences with their charisma and musical talent.
