Danny Boy is a ballad written by English songwriter Frederic Weatherly in 1913, and set to the traditional Irish melody of Londonderry Air. Various interpretations of the lyric exist, some suggest the song to be a message from a parent to son going off to a war, or an uprising, or leaving as part of the Irish diaspora.

The Londonderry Air originated in County Londonderry, Ireland. It is popular among the American Irish diaspora, and is well known throughout the world. The tune is played as the victory sporting anthem of Northen Ireland at the Commonwealth Games. Beside Danny Boy, there are many other lyrics set to the air melody.

Oh, Danny boy, the pipes, the pipes are calling
From glen to glen, and down the mountain side.
The summer's gone, and all the roses falling,
It's you, it's you must go and I must bide.

But come ye back when summer's in the meadow,
Or when the valley's hushed and white with snow,
It's I'll be here in sunshine or in shadow,
Oh, Danny boy, oh Danny boy, I love you so!

But when ye come, and all the flowers are dying,
If I am dead, as dead I well may be,
You'll come and find the place where I am lying,
And kneel and say an Ave there for me.
And I shall hear, though soft you tread above me,
And all my grave will warmer, sweeter be,
For you will bend and tell me that you love me,
And I shall sleep in peace until you come to me!
