Here's a lyrical version with a focus on melody and rhythm:
(Verse 1)
If you miss me, look up high
I'll be in the sky, I'll be shining by
If you feel lonely, lost in the night
Look up at the sky, I'll be your guiding light
(Chorus)
I'll be your moon, your evening star
Be my promises, near and far
Even if you can't be my sunflower bright
You can be my evening promises, my delight
(Verse 2)
If you're surrounded by darkness and fear
I'll lead you through, I'll be always near
I'll be your moon, your shining light
Be my evening promises, my heart's delight
(Chorus)
I'll be your moon, your evening star
Be my promises, near and far
Even if you can't be my sunflower bright
You can be my evening promises, my delight
(Bridge)
Who will guide me through my darkest night?
You're the one who shines my light
Like the moon in the sky, you illuminate my way
Be my moon, my evening promises, every day
(Chorus)
I'll be your moon, your evening star
Be my promises, near and far
Even if I can't be your sunflower bright
I want to be someone's evening promises, shining light
(Outro)
Be my moon, be my evening promises
I'll be your moon, I'll be your evening promises
Forever and always, I'll be there for you
Be my moooooon.
