A song written from the perspective of an astronaut who is missing the woman he's in love with back on Earth.  Guess I wanted a song with the word 'midnight' in the title, and I also wanted a song with the word 'moon' in the title, and as I was writing one or the other, it made sense to include both words in the title of a single song.  Not that you can hear the inspiration in this, but one of my favorite albums of all time is Dark Side Of The Moon by Pink Floyd.  Rather than attempting to write in that vein though, I was instead motivated by noticing that a lot of great old American songs that are now considered standards have one of those two words in the titles - a lot of vocal jazz from before there were a million different jazz subgenres.  Same is true for the word 'train' and 'angel' - of course I've written songs with those words in the title as well - not together, but you know what I mean...haven't released those because they didn't turn out well enough.  I think that Police song that had the word 'moon' in it also may have influenced me, because I wanted a prominent bass line like Sting played in his.  And then having the slide guitar sound in there represented a sound effect you'd think of when a rocket is blasting into outer space towards the moon.  Weird reasons to write a song, but that's what I remember thinking about when I sat down to write this.
