Asus4         A                 G             D
 If you're travelling to the north country fair
Asus4                   A            G     D
 Where the winds hit heavy on the borderline
Asus4        A         G             D
 Remember me to the one who lives there
     Asus4       A     G            D
 For she once was a true love of mine


Please see for me if her hair ain't so long
And flows in curls down her back and breast
Please see for me if her hair ain't so long
For that's the way i remember her best

Oh see for me if her coat's pulled up close
And her braid frames her sweet pretty face
Oh see for me if her coat's pulled up close
For I'm exiled in a lonely place

Please see for me if she remembers me at all
Oh a million times i've hoped and I've prayed
In the darkness of my nights
In the brightness of my days

So if you're travelling to the north country fair
Where the winds hit heavy on the borderline
Remember me to the one who lives there
For she once was a true love of mine

    Asus4       A     G            D
For she once was a true love of mine
