"Cornelius Cardew very famous in Britain, because he was the darling of the avant-garde, and he played in a band called AMM, which was an improvising band in the '60s. Paul McCartney used to come watch them. Later on in life, he became disenchanted with avant-garde music, because he felt it couldn't reach the public. It didn't have a wide enough appeal. So he'd take these tunes of old English folk songs and write Stalinist lyrics over the top of them. I do think that when he changed to folk songs, he actually lost the tiny audience he already had, which is quite interesting."
