IMHO, Nate Evans' Temptations Revue sounds closer to the original Temptations, than Big O's Temptations.

I know I'm treading on sacred ground...

Truth be told, Dennis Edwards, Glenn Leonard, and Richard Street's Temptations Revues and some of The Temptations' tribute groups featuring Larry Johnson and others, could and would give Big O's Tempts a run for their money!
