... so i was in scotland ten years ago, sitting in the teviot row house, and the band played this song, the chorus of which i havent been able to get out of my head since ... and now i find theres a whole plethora of lovely folks who enjoy this type of music and might just know the rest of the song! anyway, as best i can tell, the chorus goes like this:

shes the earl of march's daughter, the fairest of them all and the humble squire, tashie law? has taen her heart awa'

... the song fascinated me because it has the traditional poor rover type hooks up with noble young woman theme, but with a bizarre twist at the end where he rides back from war to find her wasted away to the point he doesnt recognize her and doesnt believe she is his love ...
