I believe the lyrics are (as I learned them at Echo Hill Camp):

In the Land of Oden, of Oden
There stands a mountain, a mountain
Ten thousand miles in the air

From edge to edge, edge to edge
That mountain measures, it measures
Ten thousand miles square

Once every million years, a million
A bird comes winging, comes winging
Sharpens its beak
And quickly disappears, and quickly disappears

And when that mountain, that mountain
It wears away, away
Then will eternity be
one single day, will be one single day

Repeat first verse.

Thanks for the chords,
