Here is a classic Lennon and McCartney song that was heartfelt and emotional when the Beatles sang it in 1969 and remains an emotional song today. “Mother Mary” referred to in the lyrics is not a religious figure but rather Paul McCartney's mom who was assuring her son that everything was going to work out for the best as the world's most popular musicians struggled with the strains of touring and meeting recording deadlines. A message we all need to hear and remember.
