This is not only the worst book I have ever read about Wagner, but probably the worst book I've ever read on any subject. Witless, so full of mistakes one doesn't know where to begin, unfunny (all the worse, because the author clearly takes himself for a wit); full of tedious conceits (examples: 'When to visit the restroom' and 'Rough spots and how to get through them').If you want a rest, stay at home. If you want to pee (or piss) during an interval, say so: it would be unusual to find anywhere to rest where you're going. If you find Wagner tedious, go to a musical. If you want to read an illuminating book on Wagner, buy Bryan Magee. If you should happen to need some absorbent paper for one of your visits to the 'restroom', buy this book. Actually, don't - it isn't even cheap.Richard Miles
