by the Real Mckenzies
These chords are 100% correct. With standard tuning you can play along with the song on 
album, which is what I did to get this right.
(the chord in the first verse/chorus repeat through the entire song.

Well I've lived me a life of stearf and strife
On mony a bloody battle plain
But it breaks my heart I must depart
And nae avenged I be

So take these bands frae aff me hands
And bring to me my sword
For there nae be a man in all the land
I'll brave him at one word

So farewell light and me sun shine bright
And all benath the Highland skies
MacPherson's name will nae distaine
The wretch who will nae die
