I like the Corries' original version as it is quite gentle and reflective, not like some of the tuneless and rather aggressive renditions you can get around sporting events. I believe Ronnie Browne said he would not sing it again at the Scottish Rugby Internationals. after the time you mentioned, Miranda, as he found it too emotional.
The usual scenario now at rugby internationals at Murrayfield is that the pipe band of the day will play the first verse, with people singing along, but then they cut out for the next verse (actually the last verse as they miss out the middle one) and the crowd sing that last verse a cappella. That in itself is quite stirring. Maybe my favourite version.
