The full title of the last track is "Dove across the water"
Track 4 air
The pipe air in the middle of the song is "Lord Lovat’s Lament" which is transcribed on this site.
I’ve always thought it sounded unspeakably sombre, and now i understand why. The tune ‘Lord Lovat’s (1667-1747) Lament’ was composed by his loyal piper, David Fraser (1716-1812). Lovat was defeated at Culloden and convicted of treason against the British and was beheaded, on Tower Hill, the last person to be so in Britain. There is another discussion thread on the subject too.
