To keep the record straight, it wasn't always John and Yoko. We've all accused one another of various business things; we tend to be pretty paranoid by now, as you can imagine. There's a lot of money involved.

My model for business is The Beatles: They were four guys that kept each others' negative tendencies in check; they balanced each other. And the total was greater than the sum of the parts.Great things in business are not done by one person, they are done by a team of people.
