Here are the partial lyrics to the first verse...

Ah, the rugged misty Isle, the Isle of Skye doth loom, Jagged line of blue, ???? in the twilight gloom, And the water troughs, swift cutting ??? my boat to you, And tonight again 'twil lighten, ?????????

I hope this and the fact it was recorded by Kenneth McKellar will jog soneone's memory.

Thanks!
