That's the song I have sung to both of my kids. I even have a made up second verse for them ;) So the other night before Hannah went to bed we were "loving" on my bed- talking, snuggling, etc.. I proceeded to sing it to her. It's been a while since I have. She sat there and listened real sweetly, then said when I was done-
"But mom it'll be ok."
"what will be ok babe?"
"it's ok if I run away"
"if I run away I'll be right back ...."
"Hannah what are you talking about?"
"If I run away. I'm your sunshine, I won't take it away. I'll be back"
