With a bottle of rum

Atop the rooftop I hum

This nyctophile I've become

Awaiting...

Ah! The night has come.

Beyond a glimpse doth she bestow upon me

A colossal crystal-white pearl do I see

Big and bright

Just like you lit up my life

She lights up my night.

Night is when you and I meet

Night is when my heart is complete

Both together in the dark hour

Gazing up at one moon

Night owls, you and I are.

I scan the skies, searching for thee

Ah! There you are, shining down on me

O, beautiful brightest star tonight

I wish, I wish, for the black swathing my arm

To fade into white. For everything to be right.

I ask for too much. You are gone. Just another chapter

In my long lonely book. But our child, I named after

She who stayed with us, our love's understanding queen

Lending her light

for you to shine bright

Bless her sheen, 

O sweet Selene.

So a couple of things in case you didn't realise. 

1. Selene is the Greek Goddess of the Moon. And yes, the child was named after Selene. 

2. The 'black swathing my arm' would be the black armband, the sign of mourning in the Western parts of the world.
