This Bullpen Bulletins page (from the weeklies dated 21 December 1983) includes a report on a visit to Redan Place by TV-am's (which launched earlier in the year) Saturday morning kids show DATA RUN (predecessor for the Wide Awake Club).
I have the very vaguest memory of seeing this report at the time. I seem to remember that the (by now long-defunct) PLANET OF THE APES weekly was mentioned. Does the memory cheat? Am I thinking of a different programme? I'm really not sure.
As I've mentioned before, TV-am's archive appears to be well preserved so - possibly - this episode still exists.
