A Truly Curious Mashup

It may be hard to wrap your mind around this mashup. The lyrics are "All-Star" by Smash Mouth. The tune is "Walking on the Sun" by Smash Mouth. And the video is "Smooth" by Santana with Rob Thomas of Matchbox 20. Does a song you've never heard before make you nostalgic for the 1990s? (via Metafiter)
