“Where Is The Old Man?
Words and Tune by BURL IVES

This song was thought up during a few quiet moments at the end of a day in an army camp. Who is the old man? Where's he gone? “ – – Nobody knows” – probably one of the characters of an ancient ballad come to haunt us.

Slowly (meditative
Where is the old man who lived high on the hill,
Who lived on the hill so long?
Where is the old man who lived high on the hill,
Who made his whiskey and many a song, a song,
Who made his whiskey and many a song?

He's gone far away, nobody knows where,
He's been gone ever so long:
But at night when it's still at the top of the hill,
You can still hear the sound of his song, his song,
You can still hear the sound of his song.”
[Burl Ives, Volume 1, “The Wafarin' Stranger” A Collection of 21 Folk Songs and Ballads, ed. H. Haufrecht, 1945]
