May be worth contacting the beeb regarding Week Ending as even in the 70's/80's they weren't keeping stuff. Probably 10+ years ago now I sent the beeb a complete run of series 2 of a
radio comedy called Tonys from 1981 as they hadn't got them so I suspect they will have gaps for Week Ending. I was in a group that pooled comedy recordings (thats how the Beeb
found I had the Tonys recordings) and there is a l
list of all episodes of Week Ending in the hands of members. Dont suppose you know the actual dates of the recordings?
TTFN,
Jon
