I don’t think that whole choir segment came across as particularly racist, but it did come across as lazy and ignorant...it wouldn’t have taken five minutes for her to do a couple of quick Google searches to get her facts straight, about the choir, about the Lion King and the provenance of its music etc. rather than blathering on about “Africa” as if it’s a country, rather than an enormous continent with many different cultures and languages. If you really were so worried about how you came across, wouldn’t you just do a quick Google check and then film and say “heard this amazing choir, and I’ve just been learning a bit about x and y”?
