to be fair, the "rules" for those sessions is that each band has to do an original along with a cover, so they just decided to do a joint cover with I Kill Giants, who they were on the road with. it was thrown together pretty quickly, since both bands were touring and didn't have a ton of time, and they chose "Soco" because everyone knew it. I do understand that it wasn't the best cover, but it was just a bunch of guys having fun.
You've got a point. But they didn't need all those people to sing two vocal parts. I just really thought of all the bands to cover that song, those guys would have come up with something..."old gray-ish." And half of the guys looked BEYOND bored.
I'd still love to hear them do a studio version with some of their flare in it.
