Some popular cultcha, and some trivia. First, Scottish folk/rock band Runrig's version of "Loch Lomond":
I only just learned the "story" behind this song, it's about two Jacobean soldiers, captured as they retreated from England. One is to be hanged, and one set free. That's the low road and the high road: the one to be hanged is taking the "low" (underworld) road back to Scotland (so he'll be home first). The high road is the real road.
Anyway, even without the little snippet of trivia, it's worth a listen.
