Once, as my heart remembers,
Gb Db
All the stars were fallen embers.
Bbm Gb Db
Once, when night seemed forever
Ab Db
I was with you.
Once, in the care of morning
In the air was all belonging.
Once, when that day was dawning.
I was with you.
Bbm Gb Ab
How far we are from morning
Bbm Fm
How far we are
Bbm Gb Ab
And the stars shining through the darkness,
Bbm Ab
Falling in the air.
Once, as the night was leaving
Into us our dreams were weaving.
Once, all dreams were worth keeping.
I was with you.
Once, when our hearts were singing,
I was with you.
