All I can say is....oh! my! gosh! This HAS to be the funniest thing I have seen for a while.
To set it up....remember back in the 80's when a bunch of big name musicians at the time got together and recorded a song for Africa (or something like that...?) It had Cyndi Lauper, Michael Jackson, Stevie Wonder, Lionel Ritchie, Tina Turner, et. al. Just a bunch of them.
Well.....a bunch of Japanese impersonators got together and re-made the song. It's freakin' funny!
