This is a fantastic Runrig song for Scots/Gaelic weddings. I enclose the gaelic and English (mistakes are 100% mine) I think the lyrics are a fair representation of what's ahead!
The Cycle of the Ocean/ Cearcall a'Chuain

We are all upon the Ocean
Steering our course through life
Sailing a mysterious boat
Lost in the grasp of the Ocean
With the wind at our back
The boat maintains its course
And neither time nor the sea
Will fright us from our wits nor support us

The Sea is calm
She is wild,         She is wide
She is beautiful         She is forsaken
She is spiteful                 and profound
O But we, we are blind
There is nothing belongs to us but Life
Hoist the sail! Lift the oars!
Till we find our headway in it

But it is my hope, it is my hope
That when the Sun goes down
They will see me steering for the West
Over to Uist on the circle
The Circle of the Sea
Forever will she turn in my favour
To the fair lands of the West
Where does the day not begin?


Cearcall a' Chuain

Tha sinn uile air cuan
Stuireadh cuairt troimh ar beatha
A' seoladh gheola dorch'
Air chall an greim na mara
Tha a ghaoth air ar cul
Tha a'gheol a cumhail roimhe
S'cha dean uair no an cuan
Tonaisg dhuinn no rian

A mhuir tha i ciuin
Tha i fiadhaich    tha i farsuinn
Tha i alainn                 tha i diamhair
Tha i gamhlasach                 is domhain
O ach sinn, tha sinn dall
S'chan eil again ach beatha
Tog an seol, Tog an ramh
Gus an fhaigh sinn astar ann

Ach tha mi'n duil, tha mi'n duil
Nuair a bhios a'ghrian dol fodha
Chi iad mi a stuireadh an Iar
Null a dh'Uibhist air a' chearcall
Cearcall a chuain
Gu brath bidh i a' tionndadh
Leam gu machair geal an Iar
Far an do thoisich an La
