Though it has been argued the title is "Bright Morning Star" (ie singular), the plural fits the words "are rising" below

The Incredible String Band version is

Bright morning stars are rising.
Bright morning stars are rising.
Bright morning stars are rising.
Day is breaking in my soul.

Pale mist is softly fading
Pale mist is softly fading
Pale mist is softly fading
Day is breaking in my soul.

Friend they are all gathering
Friend they are all gathering
Friend they are all gathering
Day is breaking in my soul.

Bright morning stars are rising.
Bright morning stars are rising.
Bright morning stars are rising.
Day is breaking in my soul.

They also did a slightly similar a capella song called "Sleepers Awaken" on the Changing Horses album, I think
