This is two versions of the same song.  Rarely do you get to here two versions of the same show that represent the two people who wrote the sing.  Venus Stopped The Train was written by Jeff Tweedy and Jay Bennett.  On the Wilco version of this song Jeff Tweedy is singing.    Jay Bennett is sinning on his version of the song.  Both versions of the song are great, but they are also very different.  It really shows how every song you hear has some many possibilities.
