Another lost performance, I fear, Jamie - assuming it went ahead as scheduled.
The idea of 'Late Night Line Up' - of which this was presumably a strand, same production team - was that it went out live last thing before closedown and was potentially open-ended (eg. an interesting discussion would be allowed to run on). Unthinkable nowadays.
I asked DM if he had any recollection. He said he's not sure what his movements were last week, let alone 45 years ago, but he wishes us well in the search.
