A good friend is a lawyer in the music industry. His bread and butter is drawing up contracts for recording artists, and getting them a better deal than they had before. Typically, in the 60's and 70's a new young star or band would be showered by their manager with a lavish lifestyle and lots of eager sexual partners. The stars had no real interest in the contracts that they were signing or the terms of any royalty payments. They were young and naïve and thought they were in heaven.
Fast forward a few decades and they realise that all they can actually do to earn a living is "keep on rocking". The terms of their original contracts didn't build them a nest egg, spivs took the vast part of the earnings that should have come to them, and so they carry on. It's really rather sad. A lot of them effectively had their pensions stolen from them by people they though were their friends when they were much younger.
