Westwood has been posting freestyles from his old shows on Youtube and Soundcloud. Some of them have already appeared on this blog before but obviously he's got them straight from DAT so the quality is significantly better than my rips. TDK has taken it upon himself to collate a load of them together into an hour long mix. Go here and check it out.
Shame Tim has been binning the DATs of any shows that weren't labelled with a guest's name. All the more reason to salvage what's not already online though, so get in the shed/loft/spare room, find the shoebox you haven't touched since '99 and send me the tapes/files so I can get them out there!
