Hello, I'm Mr. Vernon. I noticed that you added or changed content in an article, List of highest-attended concerts, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at the tutorial on citing sources, or if you think I made a mistake, you can leave me a message on my talk page. Thank you. Mr. Vernon (talk) 06:02, 11 February 2020 (UTC)
