good morning merry sunshine

i was just thinking about this song the other night. it has been so long since i heard it. the last time i heard this song was when i was a little girl and my father use to come into my room and he use to take out my 45 record i had with this song on it and he would start the song and he would sit at the end of my bed and he would sing this song to me every morning. if any one has an idea of the correct singer for this song i would love to have it. every time i try and look up the song by title on google to see who sings it it keeps giving me the wrong person.

any help would be much appreciated
