If memory serves me correct, there was a drama made by the BBC - in the 1980s? - which was a satire on Maggie Thatcher, and it features songs by Alan; but it was never shown. There was some fuss about this - it was seen as an act of self-censorship by the BBC, scared of what the Thatcher Government would say (although BBC executives denied this).
Does anyone remember anything about this?

This rings a few bells drddrd so I am doing a search.

I have sent an enquiry to BBC Archives perhaps they may
be able to help.

Can't promise I will find anything but you never know.
