The show has the unique concept of celebrity couples competing against one another.

"In which case it will be an enduring, unique concept."

It is a unique concept, I will grant you that.

The basis of the unique concept is a voice.

But it is entirely possible that each person believes in a unique concept.

A unique concept, yet one that must work in Gerard's case.

Despite the unique concept, the game received very bad reviews as there was little to do once a fighter had been created.

The show has a unique concept never seen before.

The product incorporated a number of unique concepts and technologies.

But it was a unique concept and much good work was done.
