South Korean pop star RAIN has been forced to cancel his planned tour of the United States after an American band called Rain filed a lawsuit against him. The singer, real name Jung Ji-Hoon, was set to begin his U.S. tour on Saturday (15Jun07), but has postponed the gigs after he was served by the suit. The band Rain sued the 25-year-old singer in a Nevada court in February (07), protesting at the latter's plans to use his name in the U.S. Star M Entertainment, organiser of the singer's world tour, says, "We have postponed the U.S. tour. We will push for it as soon as the legal case is settled."
