I just heard the chorus, so tender and sweet like a lullaby - as sung by Father Pablo Straub on EWTN just yesterday. He sang it with the words, "Full of grace" instead of "Mother of God." I was enchanted by it. I am going to sing it all the time and teach it to our new tiny twin grandsons when they move back to Omaha. It was in 1959,he was just ordained a priest and was in a school yard back east, when the children began to sing:
Hail Mary Full of Grace
Lady in Blue - I love you
Hail Mary, Mother of God
Mary is my mother, too.
Glad I happened by here...now I know the entire song!
