"I did, I did think that was wrong, and I was wrong!" Waters tells host Stephen Sackur. "Of course I was. Who cares? It was a commercial decision and in fact it’s one of the few times that the legal profession has taught me something. Because when I went to these chaps and said, 'Listen we’re broke, this isn’t Pink Floyd anymore', they went, 'What do you mean? That’s irrelevant, it is a label and it has commercial value, you can't say it’s going to cease to exist, you obviously haven’t looked back to Runnymede, you obviously don’t understand English jurisprudence… It’s not about what you think, it’s about… it’s what it is'. The law is everything what we have, that’s what The Wall is about."
