Some Greenwich dancers got expert help Tuesday as they prepare for a competition that's for a great cause.

They rehearsed for the second annual Dancing Stars of Greenwich dance-off gala.

Proceeds benefit Abilis, which provides services and support for individuals with special needs and their families.

Former "Dancing with the Stars" champion Tony Dovolani is helping with the choreography. He says dancing is a great sport for everyone.

The show is Saturday at the Tamarack Country Club in Greenwich.
