If you're in pop music, you've got to deal with the changing of the guard every few years. By the time the '70s arrived, I was well aware of the cyclical nature of the game. Pop music is a creature of the moment; it thrives on the mood of its time. Either you hook into that or you're not going to be part of it.

This rise of the new global mega-rich is happening as established institutions are falling. The fall runs the gamut from the music business and traditional media to the Detroit automakers who find themselves obsolete, outmaneuvered, and out-priced by entrepreneurs in Silicon Valley, Mumbai, Shanghai, and even Siberia.
