i've just googled it... reading the lyrics... (SPOILER ALERT, READ THE REMAINDER AT YOUR OWN RISK!!)
"I'll Be Right Behind You, Josephine" the comma before the last word of the title speaks volumes.....
i'm pretty sure its from the perspective of a guy in a coma... he's accepting he's going to die...
My take on the title:- he's saying to her "If I could speak, I'd agree with you that it was time to switch off the life support"
haunting, powerful,beautiful... and will stick with me for a long time
