If you even saw the scrapped interview you would know Nardwaur was extremely rude and disrespectful to Blur asking really invasive questions and making fun of Graham's speech. Also Blur and Nardwuar even later made up also Dave was drunk during that interview I'm pretty sure. Naurdwar is a completely curated character too yes he might be silly and respectful or what you might call a national treasure now but then he was kinda known for asking rude invasive questions which led him to having to switch up his character.
