Mock's Crest Productions, supported by the University of Portland, stages the Gilbert and Sullivan classic operetta. It revolves around two recently married gondoliers in Venice, one of whom, it is discovered, is the King of Bartaria.
The shows are dedicated to the late Roger O. Doyle, who died in April from Amyotrophic lateral sclerosis ("Lou Gehrig's disease"). Doyle devoted 40 years to the university's performing and fine arts faculty, and brought comic opera to campus and the community for 20 years.
