Actually, I knew the people he mentions in Oxford in the early 1960s. I'd add the following anecdote. I used to put the SPGB position to them that it was Marx's view that there'd be no money in a socialist society. They pooh-poohed the idea. After all, they were essentially leftwing Labourites (there's a letter from one of them to the Socialist Standard here ). They had invited Tony Cliff to address a meeting. I asked him whether or not Marx had said there'd be no money in socialism. He shocked them by replying that Marx had said this (he recognised where I was coming from of course).
