Even though he's usually a back-up singer and doesn't have as much fame as his fellow band members, he doesn't sing half bad. Well, it's the best Japanese singing from a non-Japanese person at least. At least, I don't think he's Japanese. He's actually the only male member with both short and normal hair. Everyone else seems to have it either long, dyed, or bleached.
