Nevada has become the latest US state to make it illegal for musicians to falsely claim they are connected to well-known groups.
Bands must now call themselves 'tribute' acts unless they have at least one member historically linked to the original.
The law covers Las Vegas, which is renowned for its live entertainment.
Mary Wilson of The Supremes lobbied for the law after unsuccessfully suing five other acts performing as the group.
Surviving stars from The Drifters, Sha Na Na, and other bands also welcomed the move.
Authenticity
Platters star Sonny Turner said: "Nevada is the entertainment capital of the world, so this was one of our major goals."
Maxine Porter, manager for original Drifter Bill Pinkney, said: "In a town like [Las Vegas], where you have a constant flow of tourists, this is a place where people expect to have authenticity.
"You don't need to see the Drifters advertised on three different marquees," she said.
She added that she hoped to see the bill become law in at least 20 US states by the end of the year.
If bands make false claims, it will be considered as deceptive trading practice under the new legislation.
Pennsylvania, Connecticut, Massachusetts, New Jersey and Illinois are among the other states with similar legislation.
