Same as others here I like 'em in the right place and if they are good (Kippers, Rambling Syd Rumpo, Stanley Accrington etc.)
What I would ask is what do the anti parody people think of parodies which do not mock a particular song but a particular event or person? Eric Bogle's "I hate wogs" immediately springs to mind - mercilessly sending up racist attitudes in Australia. The other thread running at the moment about Star Trek could be another?
Surely there are many parodies which do not in themselves send up someone elses music but do poke fun at someone or something else. How do we feel about these? Or are these not parodies at all???
