What a blessing to find all this info. While visiting my mother recently she told me about her dad singing this song about two little girls in blue and how she would like to know all the words to this song. I know she will be so pleased to hear this sweet tune from her past. I'm going to see if my son can play it on the piano for her on our next visit. Her dad would sing this back when she was a kid. She was born in 1932, also he would sing the letter edged in black. Music transports us across time, this will surely bring a smile to her face. Thank you one and all!
