As soon as the piano rang out the first chords, I audibly yelled "Nooooooo". Almost 3 years ago, I sang "Lullabye" to my daughter in a dark, almost empty room in the NICU at 2am. My wife was recovering from the emergency c section and couldn't even hold our first child. I was relaying updates as best I could, not knowing who to spend my time with, and going crazy running around the hospital. (We're all happy and healthy now, fwiw) I was exhausted, scared, and pacing the floor when the lone nurse said "Sing to her. She knows your voice". So I sang this song. I am a half decent singer and even though I wasn't at my best, I think it calmed daddy and baby down, but left the nurse in tears. She apologized, saying she lost her dad the previous year and he sang it to her all the time.
I used a lot of words here to say that I cried a lot watching them do this song.
