The title pretty much illustrates the type of humour in this book, puns of all sorts. I hadn't read anything else by this author so it took me a while to realise that the world in this series is a world of animals and magic can be worked through music. The magician behind the duar (guitar), however is a sometime law student, sometime rock musician, from San Francisco who arrived by accident in the first book of the series. He takes songs he knows from the world of rock & pop, twists the words to suit the situation and sings it. He's a little erratic, however, so he can't guarantee the results, as his friend the otter is forever reminding him. The two friends set out to help a phrase of music find its composition because they are bored with inaction, but the pleasant summer trip is interrupted by the need to rescue a group of princesses from a collector who has them caged in his country house. They have everything they could want except the right to leave and that's the one thing they do want: the bonobo princess, the otter princess, the mountain gorilla princess, the ocelot princess, etc. It's full of puns, rock songs, animal jokes and magic. Lots of fun. (There's even the "Badges? We don't need no stinkin' badges!" adapted perfectly to the narration and I will never forget the pin stripe suited owl and his brief case full of bureaucratic bumpf.)
