'Help!' (1965) was the Beatles' third US #1 single and the title song of their second film. Written mostly by John Lennon (at age 22), it was meant as a sincere call for help amid the chaos of Beatlemania — John himself called it a 'genuine cry' of feeling overwhelmed. Its catchy pop-rock melody contrasts with the earnest lyrics ('Help me if you can, I'm feeling down'), marking a shift to more personal themes. In October 1965, the Beatles even performed 'Help!' live at Shea Stadium via a pioneering satellite link to Europe, making it one of the first truly global rock broadcasts.
