Abba are the latest stars to join the ringtone revolution - allowing mobile phone customers the chance to hear their hits every time a call comes through. The Swedish superstars have agreed a deal with Universal Music to make their songs, including the appropriate RING RING, DANCING QUEEN and MONEY, MONEY, MONEY, available as 'truetones' - which sound more realistic. MARTEN GLANDER, managing director of Universal Music Sweden, says, "Abba have always been very thorough in every new area they have entered, and as a result they always come out on top. "Now it's great to have their involvement in, and devotion to, this latest enterprise - distribution of their music through mobile phones."
