yup,it's runrig, i know this as a scottish person and this plays absolutely everywhere in scotland at the end of night in a club etc! i've recently got it started playing at the end of the night in the club in the village where i live in a tiny village in devon now, only because the dj is scottish too! it's by runrig and it's a scottish classic! the live version is the best, and yes, it starts slow "by yooooon bonnnnny baaaaaaaaaaaaaaanks, by yoooooooooooon bonnnny braes" etc and ends up a total kilt flinging free for all, everyone jumping around and och-ing and aye-ing! great fun when ******, but not really sure when sober! hope this helps! love tabby cat x
