I don't think an actual soundboard copy circulates, but there is a lossless FM copy I found on archive.org (in FLAC):

The country sounding song was Houston #1 btw, also some of the stuff planned for the last album is like unreleased stuff, FOP is the only one I have confirmed
Expect stuff like Car Kids, LIALD, The Race, FOP, WB
There was this whole Coldplay.zip file too that's unavailable now. I wonder if that had songs/snippets from what is planned to be their final album since Chris has said that it'll be self-titled.
