If you don't tour, you cannot expect to sell a huge numbers of your albums either. It was both a business - and an economical decision and we wanted to play anyway. We just wanted to get out for the tour when it was safe enough for us.

Traditionally the show must go on which is a stupid thing to say, but that in a nutshell is what's going on. We have a new record out; if we won't tour, the new record dies. It's reality - it's what business is nowadays. You just need to tour to sell your albums.

By the mid-70s, I wanted to get out of the business. I was tired anyway.

Chart numbers can be deceiving. An album doesn't have to sell that much these days to show up really high on the charts.

Comedians do movies and TV so that when they tour, they sell out. That's the goal: To get popular enough so the place is packed.

Just getting a degree is not enough, and you need to sell your ideas.
