Putting in a plea for a technical magician to post a blue clicky for something from the lady herself!
My personal preference would be for a clip from "Wasn't that a Time!" featuring Ronnie rehearsing 'Venga Jaleo' ahead of the reunion concert. And I know there's also a video clip of Ronnie and Holly Near talking over and singing the song about the Disappeared in S America. (But not, please, any of the TV programme appearances, which seemed quite at odds with the live experience.)
But might there not also be audio clips from various Weavers LPs? What about the great Round the World medley, where the wonderful energy of the whole group and its rhythmic 'engine' was displayed?
If a magical elf -- Mr Joe, please? -- could accomplish any of the above, I would consider that my Christmas had come early!
