The Girl I've Left Behind Me AKA: Brighton Camp 
I'm lonesome since I cross'd the hill And o'er the moor and valley Such heavy thoughts my mind do fill Since parting with my Sally I ask no more the fine or gay For each but does remind me How swift the hours did pass away With the girl I've left behind me 
Oh, ne'er shall I forget the night The stars were bright above me And gently lent their silv'ry light When first she vow'd to love me But now I'm bound to Brighton Camp Kind Heaven, then, pray guide me And send me safely back again To the girl I've left behind me. 
Had I the art to sing her praise With all the skill of Homer, The only theme should fill my lays -The charms of my true lover. So let the night be e'er so dark, Or e'er so wet and windy Kind heaven send me back again To the girl I've left behind me. 
Her golden hair, in ringlets fair, Her eyes like diamonds shining, Her slender waist, with carriage chaste, May leave the swan repining. Ye gods above! oh, hear my prayer, To my beauteous fair to bind me, And send me safely back again To the girl I've left behind me. 
The bee shall honey taste no more, The dove become a ranger, The falling waves may cease to roar, Ere I shall seek to change her. The vows we register'd above Shall ever cheer and bind me In constancy to her I love, -Ye gods above! oh, hear my prayer, To my beauteous fair to bind me, And send me safely back again To the girl I've left behind me. 
The bee shall honey taste no more, The dove become a ranger, The falling waves may cease to roar, Ere I shall seek to change her. The vows we register'd above Shall ever cheer and bind me In constancy to her I love, -The girl I've left behind me.  

Irish Song Lyrics

Additional verses from Songs of the Irish in America, Meek. 
She says,"My love, come home to me My friends are rich and many; Or else abroad with you I'll roam A soldier stout as any. If you'll not come or let me go I'll think you have resigned me," It broke my heart to answer, "No" To the girl I left behind me. 
For never shall my true love brave A life of war and toiling, And never as a skulking slave I'll tread my native soil on. But someday I'll return again If the rebels they don't find me And never will I roam again From the girl I left behind me.
