Happy Birthday to You, the four-line ditty was written as a classroom greeting in 1893 by two Louisville teachers, Mildred J. Hill (born in Louisville, KY, on June 27, 1859) an authority on Negro spirituals and Dr. Patty Smith Hill, professor emeritus of education at Columbia University.
Music publisher Warner/Chappell will no longer be allowed to collect licensing royalties on those who sing “Happy Birthday” in public and had pay back $14 million to those who have paid for licensing in the past.
And so it goes
