Millennials know Rick Astley because we were all rickrolled when 4chan was irksome but had not yet given birth to the evils of 8chan and Qanon. Back when it was mostly longcat memes and nerds sharing pics of Creepychan before the world better knew her as Allison Harvard on ANTM.
I suppose Mr. Astley is sheltering in place and uploading his Post Malone, Sia, and Foo Fighters covers because we're all in a pandemic and why not.
Rick... looks better than he did when "Never Gonna Give You Up" first came out??? He wore sunscreen and moisturized!!!
