Who owns the song “Happy Birthday”?

“Happy Birthday” began as “Good Morning Dear Children” and was
written by educators Mildred and Patty Hill in 1893. In 1924, a
publisher changed the opening line to “Happy Birthday to You” and
it became a ritual to sing the song to anyone celebrating his or her
birthday. In 1934, after hearing the song in a Broadway musical, a
third Hill sister, Jessica, sued the show and won. The Hill family
was thereafter entitled to royalties whenever the melody was per-
formed commercially.
