I've uploaded my version of the Detroit release show from 89X to Lance's FTP. If there are any other sites that anyone would like it just let me know. There is a little fuzz during the intro and Use It Up, but it cleared up pretty well when I adjusted the antenna.
Lance, I've also got a copy of the Toronto show that may be a little sharper than the other one online and its in SHN format, let me know if you want it.
