It's the theme song everyone knows and loves like you've never heard it before.
Last night's 'The Tonight Show with Jimmy Fallon' had an entire segment devoted to Nintendo and their new console, the Nintendo Switch, and who came along to debut it but only the creator of Super Mario, Shigeru Miyamoto, who joined The Roots in playing the 'Super Mario Bros. Theme'.
We can't figure out who was more delighted to be performing, but we're going to go out on a limb and say it was The Roots.
