Lyrics:

Here's forty shillings on the drum
For those who volunteer to come,
To 'list and fight the foe today
Over the Hills and far away
[Chorus]

O'er the hills and o'er the Main
Through Flanders, Portugal and Spain
King George commands and we obey
Over the hills and far away

When duty calls me I must go
To stand and face another foe
But part of me will always stray
Over the hills and far away
[Chorus]

If I should fall to rise no more
As many comrades did before
Then ask the pipes and drums to play
Over the hills and far away
[Chorus]

Then fall in lads behind the drum
With colours blazing like the sun
Along the road to come what may
Over the hills and far away
[Chorus] X4
