The Simpsons (feat. Michael Jackson) - Do the Bartman (1991)......that's MJ right?

Happy Birthday Lisa by Michael Jackson and Bart Simpson. "The Simpsons" once had an episode featuring Michael Jackson. Michael Jackson was allowed to talk, but Kipp Lennon impersonated him in the song "Happy Birthday Lisa". This is the unreleased version that Michael Jackson himself recorded, circa 1991.
