This is a young Trainer Intern from Chiba, Japan named Tida Yumatsu (spelling is a guess based on Omar's pronunciation). According to Omar he sang a song by his (Tida's) favorite singer, William Hong (the excruciatingly bad singer from the real Idol)......"She Bangs". His voice was atrocious, and he was only able to remember the words because he carried a crib sheet, but his dance moves and enthusiasm were so good that the Judges gave him a pretty good review.
I wish I would have gotten a crowd reaction here because it was great, especially when he thrust his hips forward every time he said "She Bangs". My camera batteries decided to die just after he started his act and by the time I replaced them.....it was over.
