NEW YORK, Apr 21: Colton Dixon, the young singer from Tennessee known for his flamboyant hairstyle, became the fifth person voted off top-rated TV singing contest “American Idol” on Thursday night. “I wasn’t myself last night,” said Dixon, whose Wednesday performance of Lady Gaga’s “Bad Romance” was roundly criticized by the show’s judges. Dixon thanked them for their honest feedback, and assured them he would incorporate it into a future album. (agencies)
