If they ever had to recast Grease...

DANNY - Mark Salling or Jonathan Groff
SANDY - Dianna Agron
RIZZO - Lea Michele
KENICKIE - Mark Salling or Aaron Tveit
FRENCHIE - Demi Lovato
CHA CHA - Naya Rivera
EUGENE - Kevin McHale
LEO - Adam Lambert

I KNOW SOME A REALLY 'WTF', BUT DUDE, THIS WOULD MAKE ME ALMOST HAPPY THAT THEY REMADE IT.
