A former singer with the Temptations is suing the soul group and the Motown label accusing them of not paying him millions of dollars in royalties.
A lawsuit filed in Los Angeles claims he is owed royalties for the albums - Awesome and Ear-resistable.
Barrington Henderson was lead singer in the band's ever-changing line-up for five years until he was sacked in June.
He says the Temptations continue to use his image on records and on their website to cash in on him.
Henderson is also suing the group's founder Otis Williams, who is the sole original member, for making alleged defamatory remarks.
His lawyer, Brian Glicker, said Henderson was fired in June despite promises he would continue to be the lead singer.
"Williams said Henderson did not hit the right notes," Mr Glicker said.
Henderson also alleges that during his time with the Temptations the required social security payments were not made on his behalf.
Shelly Berger, president of Star Direction, which has managed the band for 37 years, said the group had not yet been served with legal papers and declined to comment.
The Temptations hit the big time in the 1960s with hits such as The Way You Do the Things You Do and My Girl.
The group's line-up has changed many times over the years and they still continue to tour the world.
