I love the live version by Silly Wizard. The late Andy Stewart sang it very well and the late Johnny Cunningham's fiddle arrangement was a fantastic accompaniment. I like the conversation they had on stage too before performing the song.

Here are the chords I use.

I'm (C) wear(G)in' aw(C)a, Jean,
Like (F) snaw wreaths in (C) thaw, Jean.
I'm (C) wear(E7)in' a(Am)a,
(E7) Tae the (Am) Land (F) O' The (C) Leal. (G)
There's (C) Nae (G) sorrow (C) there, Jean,
There's (G) neither (D7) cauld nor (G) care, (G7) Jean.
The (C) day is (E7) aye (Am) fair,
(E7) In the (Am) Land (F) O' The (C) Leal. (G)

I thought I'd share the chords I like to use.
