Here's the text as sung by Barra singer the late Calum Johnston on the School of Scottish Studies "Scottish Tradition" recording -- more than likely the source used by the Bothy Band way back when....

Thuirt an gobha fuirighidh mi
"s thuirt an gobha falbhaidh mi
S thuirt an gobha leis an othail
A bh'air an dorus an t-sabhail
Gu rachadh e a shuirghe

REFRAIN:

'S a gheala ham botham nam botham
Pe ho ro bha hin an doicheam
'S hala ham to han an doicheam
Am bothan a bh'aig Fionnaghuala

Bheirinn fead air fulmairean
Bheirinn fead air falmairean
Liuthannan beaga na mara
Bheireamaid greis air an tarrainn
Na maireadh na duirigh dhuinn

REFRAIN

All but the last line of the refrain consists of nonsense vocables based on the system known as "canntaireachd" that was developed in the highlands for the teaching of bagpiping. Calum Johnston himself was a wonderful piper.
