Cover art for Fast Blood lyrics by Frightened Rabbit

Pretty sure that first line is "Good night, it's show time."

This song is definitely about sex, but I think it's also more complicated with that.

To me, it's about how you're tortured with sexual thoughts of someone who you love after you break up.

Could also be about having sex with an ex and being confused about it.
