If it‘s your birthday soon, then at least one person will probably congratulate you with a song. Many different songs are sung around the world but Happy Birthday to You is one of the most popular (and the most recognized song in the English language). It has been translated into several other languages and it was also the first song that was sung in space – by the Apollo 9 crew in March 1969. Strangely, it is a copyrighted song. The music for the song was written by two schoolteachers in the US, sisters Patty and Mildred Hill in 1893. They had originally written a song called Good Morning to All to welcome children to class at the beginning of the day. However, the words happy birthday to you later replaced the lyrics and the song became known as 'the birthday song‘. The story would have ended there if Jessica Hill, Patty and Mildred‘s sister, hadn‘t gone to court: in 1935 she won copyright of the song. Today the copyright is owned by an American company and will expire in 2030.4º) No trecho: "… Happy Birthday to You is one of the most popular (and the most recognized song in the English language)" (1º parágrafo), há uma ideia de:
