There's at least two composers on there I recognise, I can't actually see artists at the moment, but there are several people from the art world, and several scientists.

Also: people from human rights organisations, nature conservation organisations, farmers, medics, bishops, atheists, lawyers, spies, bankers, people who work in child protection, housing for low income people, people from elite sports, people from popular sports, social workers, and lots more people without the notes to immediately say what they do.

(Yes there's also quite a lot of retired career politicians).
