Oral and Literate Traditions

I met with my honors section today after we listened to our college orchestra play compositions by African American composers. Do you think that soon we will have rock stars trying to write for the orchestra to seek legitimacy in the high art culture? Didn't McCartney try that and didn't he get knighted? It seems to me that the classical music shell is a bad fit for the more oral traditions of jazz and rock. I just remember a quote from John Lennon (I think) that when performing for a royal audience he said (approximately) If you like what you hear just rattle your jewelry.
