Have a look here ;
https://www.mixcloud.com/1spaceboss/...n-31-dec-1998/
There are links to a 320kbps mp3 rip of this on that page.
I also have a 17 year old CDR made from the original broadcast dumped to tape. From the sound of it, the band mixed the show twice ; 1 - the raw feed which is above and 2 - a 60 minute (approx) edit broadcast in Jan 1999.
UPDATE : from what my battered memory tells me the Mixcloud stream is the full show, as it seems to be identical to what I heard on the night.
