Oddly enough, what Toronto Operetta Theatre does best is operetta and the production of Romberg’s The Student Prince that opened yesterday afternoon is a pretty good example of why. I suppose, technically, that it’s a Broadway musical but everything about it, down to the humour and sentimentality seems Teutonic enough. Anyway, there’s a solid trio in the lead roles, the key back ups are thoroughly professional and the minor roles and chorus are filled out by talented and enthusiastic young singers. The band is big enough to cover all the colours of the score and the staging is appropriate and not overly ambitious. The piece gets to do its tuneful, rather bittersweet thing.
