Yes, Kenyon was responsible for some displeasing innovations which no doubt accounts for his knighthood. His self-satisfaction is very obvious; his contempt for ordinary prom-goers who enjoy great music and would gladly give Harrison Birtwistle a miss is a typical arrogance of the BBC arts world.
Anyone who calls the dreadful and historically destructive Hobsbawm in aid can be written off anyway. As a chief indoctrinator of the Open University and hero-worshipper of Stalin, his input there must have misled thousands of would-be students of history force-fed his Marxist and communist pap.
Were Kenyon still a stooge of the BBC he would be one more nail in its coffin.
