Yeah, who knows

See, I did karaoke for Otakebi Boy and Seishun Bus Guide, and also for Yuke Yuke Monkey Dance when I was in Ongaku Project. Those weren't high at all, but we did an Arashi song... I don't remember the name, it starts with several "YEH YEH YEH!" if I recall correctly, and it was tough

And then I realized the song was not that high, but the guys are very high-pitched as opposed to me. But again, I'm not a singer so I don't know for sure.
EDIT: Arashi song was Happiness. The download link still works after 2 years
