Here's a few of my favorites Sandy:

Wild Mountain Thyme- by Connie Dover (Tannahill Weavers also do a nice version)

Hector the Hero- I learned this from a dulcimer player and have never heard a recording of it. You can hear it at www.contemplator.com/folk.html which is Lesley Nelson's site. It contains a bunch of Scottish tunes ( and a lot of other good stuff) played pretty decently on midi.

Thatchers o' Glen Rae and McCrimmons Lament - by Dick Gaughan on NO MORE FOREVER (Aly Bain on fiddle)

Now Westlin' Winds-by Gaughan on HANDFUL OF EARTH
