Query: Excellent!

Richard Bonynge really deserves credit for all the disinterments he has directed in opera and, here, operetta. He always seems to know what forgotten work has wonderful music--Massenet's Esclarmonde and Le Roi de Lahore, for instance--and he revives them with style and panache. It is generally agreed among opera buffs that the lead tenor has an unappealing voice, but everyone else is fine and the music itself is really tuneful. It's also over-orchestrated, a Kalman flaw in his later work, but at least it gives Bonynge and his band something to bite into.
