Columbia University's Teacher College, a gentleman by the name of Robert H. Coleman published the song, without the sisters' permission. To add insult to injury, he added a second verse, the familiar "Happy Birthday to You."
Mr. Coleman's addition of the second verse popularized the song and, eventually, the sisters' original first verse disappeared. "Happy Birthday to You," the one and only birthday song, had altogether replaced the sisters' original title, "Good Morning to All."
After Mildred died in 1916, Patty, together with a third sister named Jessica, sprang
into action and took Mr. Coleman to court. In court, they proved that they, indeed, owned the melody. Because the family legally owns the song, it is entitled to royalties from it, whenever it is sung for commercial purposes.
