Fife was a shadow across the Forth as the Granton boat pulled out
                                     A             Bm
Over the sea and the solid earth the mist lay all about
      G                    D                    G              A
And a rising wind from the Isle of May o'er the ruffled waters strode
    Bm                             A                    Bm   G G C
And blew us a clear October day to ride on the Highland Road

          Bm
There's a winding road from Glenfarg to the mouth of the river Tay
                                       A              Bm
The mountains beckon beyond Dunkeld to lead us on our way
    G              D              G               A
Now Killicrankie's famous Pass, a battle lost and won
Bm                                        A            Bm
From the old enchanted Atholl lands, grim heart of Caledon


    D                                    Bm
The Highland Road's been sung before and will be sung again
   G                    D                                    A
As long as singers give thanks for good in the way of honest men
    G                             D             A
Let him who will be contrary, the wise man will agree
    Bm                                                            Bm
And sing again the Highland Road, the Highland Road for me


        Bm
Now the Highland Road is a rugged road, from the Tay to the Northern shore
                                     A           Bm
A man may rise in Edinburgh town and rest in Aviemore
    G                      D                     G                A
Now here's to the railroad running north and the day that gave it due
         Bm                                        A                  Bm
From the greying spires of the ancient town to the moon of the Lairig Gru

    D                                    Bm
The Highland Road's been sung before and will be sung again
   G                    D                                    A
As long as singers give thanks for good in the way of honest men
    G                             D             A
Let him who will be contrary, the wise man will agree
