CMU Daily have reported that Alice In Chains are being sued by the mother of their late frontman, Layne Stayley. Nancy McCallum claims that the surviving members of the band are withholding money she is due on revenues earned outside of Stayley’s songwriting royalties. The report says that McCallum has filed a lawsuit saying that the band are now also trying to cut her out of future payments. She says that she was contacted by the band’s lawyer last September and informed that a revenue sharing agreement that had been in place since her son’s death was being dissolved. But lawyers for the band counter that she has already been paid more than was ever due – an accountant apparently working out that Stayley’s share of revenues stands at $341,000, while she has so far received $705,000. They also added that she has attempted to trademark the Alice In Chains name. Stayley’s estate, the band’s lawyers say, will continue to receive royalties from songs which he wrote.
