I'm pretty sure John Cage's works are under copyright, which is interesting since he made such a big show of erasing himself from the work and embracing the random. It never occured to me how obtuse that was. I'm thinking particularly of 4'33". So, I guess the 'him' part of that composition is the fact that someone sits at a piano in particular, rather than say... bagpipes or even pipe organ. I wonder if it would be considered satire or a derrivative work on ukelele choir...I wish he was alive to ask him his thoughts on this.
