In the middle of her recent Japan tour, pop superstar Kylie Minogue surprised her fans by announcing a new song on YouTube. The song, written by Japanese rapper and producer Verbal, is called “We Are One” and is the pair’s effort to try to raise donations for Unicef following the March 11 earthquake and tsunami. Verbal opened for Minogue during the Tokyo leg of her tour and the Australian singer found time to squeeze in promotion for their collaboration backstage.
