I saw Mr. Love's "One in Two" at Diversionary Theatre here. The three main characters were played by actors who were very different types. The company said that the actors would interchange roles regularly throughout the run, and I thought that doing so would create quite different dynamics on stage. Never went back to test out my surmise, though.
Diversionary is on something of a roll. They are currently producing the world premiere of "Eighty-Sixed," a musical based on the novel by David B. Feinberg.
