I'd be interested in knowing what you have (and eventually getting access to them).
I found this link [link|ftp://216.243.162.145/demento|ftp://216.243.162.145/demento] in a roundabout way. It's the FTP site for [link|http://comedycorner.gotdns.com:3000/|http://comedycorner.gotdns.com:3000/]. A pretty weird link BTW. It seems that many of the early files may not have been converted into MP3 stereo files from the vinyl albums, but there's a lot of interesting stuff there.
