PBS has released a mashup of the shoe-tying, sweater wearing hero of children's television, auto-tuned and set to a piano melody by youtube artist John Boswell.
The video description says it all:
"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."
