Found the following Gaelic Christmas carol on the web, and would like to know the tune, which I take it is the traditional one to the text "An t-Eilean Dorcha", which I don't know (MIDI anybody??) This is the only apparently indigenous Gaelic Christmas song I know of except for the widely known "Leanabh an Àigh" ("Child in the Manger").

Seall Thall Tighinn Bhon Ear
Le Iain MacLeòid
Air Fonn (An t-Eilean Dorcha)

Seall thall tighinn bhon ear le sealladh bho Nèamh,
Tha daoine nan cabhaig a' leantainn na rèilt;
San stàball le leanabh tha Moire cho sèimh
Am prasaich, gun dhearain, gràdh Dhè dhuinn.

Sèist:

O reult, thoir dhomh soillse 's an oidhch' a' fàs dorch',
Mi creidsinn do gheallaidh, mo thaic thu 's mo threòir;
Cuir solas air slighe a rithist led ghlòir,
Ach am faic mi am prasaich do ghràdh dhomh.

Thàing ainglean gu talamh le moladh is seinn,
Air mòintich gach cìobair le chaoraich am faing;
Theich cadal is leum iad, le aoibhneas toirt taing,
Is ruith iad nan deann chun an stàbaill.

Cha sguir ainglean a chaoidh a' moladh a ghràidh,
San reult bidh soillse a dh'oidhche 's a là;
Bidh'm fonn ud nan cluasan 's nan crìdhe gu bràth
Am prasaich, san stàball, gràdh Dhè dhhuinn.

Hope I didn't miss any diacritics! ;-) The title appears to mean "Look Yonder From the East". I'm most interested in the tune, but would also be interested in any info on the author, date, etc., and in an English or other version if such is known.

Many thanks for any help!
