It's definitely M. Ward and Conor on lead (M. Ward starts off), and it's not Yim Yames, it's Jim James from My Morning Jacket, who it hate but supringly love in this band (except His Master's Voice - only song I'm not a fan of)

"and it's not Yim Yames, it's Jim James from My Morning Jacket" followed by "who it hate but supringly love in this band"

I think you meant I instead of it and surprisingly rather than supringly.

Sorry I couldn't help this.

I am basing this on listening and not on any other source, but it seems clear to me that it is M. Ward singing lead in the first two lines, Conor Oberst in the third and fourth lines, and Jim James in the fifth and sixth lines of each verse.

Yim Yames = Jim James, haha
