Freedom of speech is a beautiful thing. I’m not an expert on the details; while I know it means you can’t be stopped from using your voice to express your point of view; though I’m not so sure about using someone else’s.
RX seems to be of the opinion that it’s fair play, and given the results, I’ll go along with it. Though there’s plenty of mashups of George W Bush speeches this is the first time I’ve heard him cover Grandmaster Flash’s “White Lines” or “Imagine”. Give it a listen, they’re all free.
Make sure you give “Dick is a Killer” and “Let’s Get Fucked Up” a listen.
[edit: Dick is a killer seems better since Cheney got a bit handy with a shotgun -Ian]
