Jackanory 1980s Theme

Some of the Jackanory episodes, originally shown in 1980 but repeated a few times featured quite a majestic-sounding, orchestral theme. The episodes I recall that used this theme were presented by Kenneth Williams in a large chair in a set resembling an old library or study.

I can’t find any examples of episodes with this theme tune online. Does anyone remember it, and could possibly identify it?

This is drawing a blank on various forums etc. Does anyone remember the music I’m referring to, even if they can’t ID it? I’m unsure how often it was used on Jackanory - I only remember it accompanying a few KW episodes.
