Download: Spirits In The Material World (Police cover)
(update on Feb 8, '07:)The omniscient Katers just let me know that the song "was done on April 25th, 2003 in a show at Norman, Oklahoma. A fan bootlegged the show and shared it with us here [on the message boards]."
(update @ 3:51pm:)You can now add this to your MySpace profile.
I've never seen this posted anywhere before (maybe sometime in some thread on the boards, but apart from that, nope.) I love it.
