Mr. Sheets joined the Broadway company of Les Miz in 1988 and stayed, on and off, for some eight years. He began by playing the role of Brujon, but would go on to fill 12 different ensemble roles. His biggest responsibility was as alternate and understudy for the lead role of Jean Valjean. He portrayed Valjean more than 300 times on Broadway. Following his Les Miz tenure, he jumped to Phantom in a new guise, as a dresser in charge of the costumes worn by the actor portraying the Phantom.
