Was gonna mention this site - has absolute loads of random Jules shows from 2003 - 1997.. I have no idea which shows are there and what isn't.. basically this guy recorded a lot of stuff between 5-9pm on Saturdays from 1994 upwards so there's loads of Danny Rampling, Pete Tong, Seb Fontane (urg) etc etc.

It's all labelled incorrectly as well which is a bit of a pain (although the dates seem to be right, just the info that he's put totally wrong!)
