Marylin Monroe: Happy Birthday to You!

1889-- The Hill sisters in Kentucky write a special tune for the kindergarteners they taught. "Good morning to you" soon catches on and is sung in classrooms across the country. By the turn of the century, children began replacing the words with "Happy birthday to you," and the ballad becomes the most-sung song in the world. But the most famous rendition of the song was sung not by children, but by a 40 year old Marilyn Monroe, in Madison Square Garden in 1962 to celebrate the birthday of JFK.
