Rain aka Bi is considering singing the theme song for this year's Beijing Summer Olympics. The Chinese Olympic Organizing Committee recently requested Rain for the gig.

He just wrapped up filming for his minor role in the movie Speed Racer (Due to open in May), so there shouldn't be any schedule conflict this time. Does this mean Rain has to sing in Chinese? I would think so, considering all the past theme songs were in their respected native countries tongue. Maybe he can rehash the pimp classic South Korean 1988 Seoul Olympic Theme, Hand in Hand:
