Have spotted in this week's Radio Times (for non-UK dirts, it's the premier tv and radio listings mag) that the very early morning show hosted by Chris Hawkings will include a recording of u/w at Alexandra Palace in 1998. According to Chis' webpage, it will go out at 4am (UK BST). In case you're not awake then (!), or indeed if they change the time slot, then you can always listen again to the prog for up to a week from the end of transmission. See below for a webby link.
