The Nina and Frederik version was recorded on their LP album, "Dawn". The lyrics are:

In the land of Odin, there stands a mountain ten thousand miles in the air
In the land of Odin, there stands a mountain ten thousand miles in the air
Little bird come a'winging - aha
To sharpen its beak on the mountain once every thousand years
And when the mountain is worn away
This to eternity will be one single day

In the land of Odin, there stands a mountain ten thousand miles in the air
And that mountain is ten thousand miles square
Little bird come a'winging - aha
To sharpen its beak on the mountain once every thousand years
And when the mountain is worn away
This to eternity will be one single day
