Happy Birthday to You is a happy song,     1     the story behind it may not be known to all. Two sisters, Mildred Hill and Dr. Patty     2    (write) a song for children     3    (call) Good Morning to All. The song was sure to be     4     success due to    5    talents. The sisters published the song in 1893.

Thirty-one years later, a gentleman by the name of Robert H. Coleman published the song without the sisters     6    ( permit). And     7    (make) matters worse, he added a second verse, which was the familiar Happy Birthday to you.

Mr. Coleman's addition of the second verse     8    (popular) the song and eventually, Happy Birthday to You, the one and only birthday song totally replaced the sisters' Good Morning to All.
