For your viewing pleasure, here is the lost Japanese commercial for Rockman Soccer featuring dazzling animation and comedy singer-songwriter Tatsuo Kamon flying around on a jetpack. Yeah, it's pretty awesome.
For those wondering, the song is "We Are Rockman." You can hear the full version here but be warned you: it gets really, really crazy. There's a very special "moment" at 0:46. It's so bizarre, so oddly out of place that no one has ever been able to explain it. Do enjoy.
Thanks to Hikachi8 for the heads up!
