I can so relate to that! My daughter just finished a play by the high school as an orphan in "Annie" She has been singing all those songs for the last two months. An of course we had to go to several performances.
The funny thing is out of the blue my husband and I both will find ourselves singing the songs, now. I was thinking about getting her the movie for Christmas, hmmm... I may have to rethink that
.
I have attached a picture of my daughter and the girl who played Annie.
