Song of the day: Released in August 1968, The Beatles’ “Hey Jude” is one of the band’s most beloved tracks. Written by Paul McCartney to console John Lennon’s son, Julian, the track motivates to turn sadness into hope: “Take a sad song and make it better.” Its simple piano melody, soaring vocals, and iconic 4-minute “Na-na-na” coda gives you an unforgettable sing-along experience.
