I was first aware of her when she guested on The Muppet Show, I think, but I'd already seen her on television when Thoroughly Modern Millie was shown by the BBC (probably this broadcast). Carol Channing turned up as a guest on a BBC One Saturday morning show as well in the early 1980s, I think as she was on stage in London and the production team thought she was someone who could usefully communicate with children about theatre and performing, even if they didn't necessarily know who she was in the UK.
