This is an Irish folk song, I specially love the Piano (blues) cover.
The lyrics goes like this, it’s quite a sad story as it is.
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 flow’rs are dying
‘Tis you, ’tis 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
‘Tis I’ll be here in sunshine or in shadow
Oh, Danny boy, oh, Danny boy, I love you so.
And if you come, and all the flowers are dying
If I am dead, as dead I well may be
I pray you’ll 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 warm and sweeter be
If you’ll not fail to tell me that you love me
And I shall sleep in peace until you come to me.
