I only know one song with that title and it was written by John Kirkpatrick:

In the Dreamtime
Oh, long ago, long ago, all in the Dreamtime,
The creatures of the earth all spoke the same tongue... Repeat
And the earth was filled with the glory of their voices,
The earth was filled with the glory of their song... Repeat
And the language of the land was the glory of the ground,
Was the song of the earth, was the singing all around... Repeat

Is this the one ?
