"Five Minutes More" was a hit song when I was in 2nd grade,,,would make it 'about' 1946...I remember making up kids parodies of it....

My wife has been singing "Bless Em All" for several years, learned from her father's little WWII songbook....

And a woman we know does a delightful version of "There'll be Bluebirds Over the White Cliffs of Dover" on the ukelele.....those songs will be around a LONG time.
