The History Boysdominated the drama category, winning best director, actor and supporting actress, as well as best play, adding to a clutch of awards it picked up in London where it started life at the National Theatre.
The honors for musicals were more evenly divided, with Jersey Boyswinning four, including best actor for John Lloyd Young, and supporting actor, Christian Hoff.
