Happy Barking Birthday (Birthday/Children)

"Happy Birthday," perhaps the most sung song in the English language, dates back melodically to 1893. Two sisters, Mildred Hill and Patty Smith Hill, included a classroom greeting "Good Morning To All" in a published book called "Song Stories for the Kindergarten." The lyrics now sung worldwide evolved over the next 40 years from the Hill sisters' original words to what everyone now knows as "Happy Birthday To You."
