One would expect that the format, a sequence of arias not unlike that of Opera in the Park (Sept 10th, it's coming up), would become a bit predictable after a while. One would be wrong: even with a bare set (one bench, one couch in front of a black curtain) and no costumes (everyone was dressed as for their prom) they managed to infuse life in the staging, and elicit laughs from the audience. One of them was drawn when they acknowledged the minimalist set by swapping the bench and the couch during intermission. A new decor! Amazing what a little switcheroo can do.
