Advantages of this live performance include a sense of spontaneity, and the feeling of being part of a theatrical audience that is visibly and audibly having a very good time. The (reduced and partly electronic) orchestra is also visible; scenery is minimal; the onstage pirate boat, excellent for a live production, is no match for what a movie can offer. The voices are uneven, and some of them evoke Broadway more than London. But the performance is well styled, lively, and energetic. Gilbert and Sullivan's witty sparkle comes through clearly. --Joe McLellan
