I was watching a video[0] lecture about the UK NHS crisis from the 1951. In that lecture the presenter showed a video of a speech (starts at 6mins 10secs in to the lecture). There are subtitles to that speech; I have never seen such interesting subtitling. Even the coughing and laughing etc from the audience is subtitled :)[0] https://www.youtube.com/watch?v=DVwpzJw1vwo
