Oh dear, oh dear..... Well I guess it souldn't come as a supprise that some afficianado's of "serious" music have little sense of humour. Many years ago we attended a friend's performance of Schwitters' Ursonate or Sonate in Urlauten, which is sort of a very long tone poem. We giggled and laughed at times during his performance and received some rather dark looks from other audience members. However, our friend thought our take OK by him.

I wonder if Tchaikovsky's estate or the US military would come afer you for using a canon in a piece and citing them?
