JCFC...Caleb Balderstone doesn't appear as such in the opera. The equivalent would be Normanno, Retainer to the Ashtons who is really the villain of the piece for devising the whole marriage scheme in the first place. The Italianisation of Scottish characters is wonderfully absurd. I really do enjoy Donizetti, it's all so entertaininly hysterical. He wrote an opera which I long to see 'Emilia Di Liverpool' but it is sadly rarely performed.
We have come a long way from Chris Kavanagh, perhaps more than six degrees of separation although, you never know, he may be an opera fan.
