This is some incredible work by John D. Boswell (melodysheep) who took some of Mr. Rogers’ greatest hits and threw some auto-tune and mash-up work in the mix.  PBS even posted this video:

“When we discovered video mash-up artist John D. Boswell, aka melodysheep, on YouTube, we immediately wanted to work together. Turns out that he is a huge Mister Rogers Neighborhood fan, and was thrilled at the chance to pay tribute to one of our heroes. Both PBS and the Fred Rogers Company hope you like John’s celebration of Fred Rogers’ message. (Headphones highly recommended!)”
