Lyrics
[Snippets]:
...life is so crazy...
...I can't take it,
but at least we've got the night...
...Bill takes me down to the beach
In the coat that he got from his father
He whispers to me that sometimes he thinks he sees things over the water
Like maybe UFOs or something...
...slow burn i'm hot like a fire
i'm sober but you're getting higher...
