Update: Why Don't You Just Switch Off Your Television Set and Go and Do Something Less Boring Instead?

 

Next to the lady, also this young teen girl in long, faded bibs, also sitting on the ground outside and standing up. Unfortunately here with a matching jeans jacket. Also briefly without jacket at the intro and walking, rear view. Boys in jeans but not bibs.

YouTube clip (full episode): "Why don't you? CBBC 1990" 

Also sitting inside without the jacket, probably in another episode.

I still don't know all episodes. (No more than this and 2 shorter clips found). And also few pics on the web.
