The founders of The Drifters are suing four musicians they claim are unlawfully pretending to be the legendary pop group.
The Treadwell family set up the group in 1953 and managed them, frequently sacking and replacing members of the group.
They allege their former British tour manager PHILIP LUDERMAN and former agent MARK LUNDQUIST are "passing off" four musicians as the real thing.
TINA TREADWELL, the daughter of late Drifters founder GEORGE TREADWELL, says, "It is my goal to rid the marketplace of all the warring factions of the Drifters so there is just one group that the fans can depend on. When something is wonderful you always have people who will copy it."
