Certainly on the chorus. And while it's clearly a song he's got strong emotions about, the verses...he just seems really deeply fatigued and having to dig deep for the spirit to get the chorus out so fiercely. Or maybe I'm just fanciful. One of this stronger songs, for sure, regardless.
I may be a conspiracy theorist, but I thought the whole purpose of kicking Carah Faye out of the band was because Season of Poison featured Frozen Oceans and she didn't want to sing something this intimate for her Jackie Baby. In my opinion, Sisley did a better job.
