"Happy Birthday to You" first appeared in print in 1912 using the melody of "Good Morning to All" with different lyrics. Its popularity continued to grow through the 1930s, with no author identified for the new lyrics, nor credit given for the melody from "Good Morning to You". Based on 1935 copyright registrations by the Summy Company, and a series of court cases (which all settled out of court), the sisters became known as the authors of "Happy Birthday to You". In September 2015, a federal judge declared that "Happy Birthday to You" is in the public domain.
