I’d completely forgotten those bits, but I imagine I took them out for one reason or another (I was never under any pressure from the BBC to cut anything unless it was to do with cost, i.e. the opening sequence). The only one I remember cutting was the woodpecker line, which was said to me verbatim but as his mother was reading the script I thought she might have guessed and been hurt, so took it out.
As to deleted scenes, BBC budgets were so tight in those days compared to movies that only studio scenes (or parts of scenes) shot on 2” video master tape would have been cut/edited down, in which case the unused tape would have been wiped and reused. In fact I don't remember any substantial cuts. The 16mm location footage may have had a few bits taken out, but no whole scenes – I have them in a barn somewhere as I was given them after the telecine edit, although they’ve probably faded beyond all recognition by now and besides, I’ve no idea what happened to the audio tape.
The only scene that was actually filmed and cut in the edit – at my urging – was Michael’s poem as I thought the performance/reading too feeble ...
