What’s Edward Allsop’s profession?

W: Edward Allsop, you seem to have had two consuming passions in your life, music and politics. Am I right?
M: Yes. I think it’s very important that leaders should have a wide variety of interests. If you are just a politician and nothing but a politician, you gradually drive yourself into the ground.  You become very inward-looking, very narrow-minded and then you don’t look after the electorate. But if you’ve got other interests, you come back to problems with a fresh mind and you can serve your electors much better than you could otherwise.
W: Where did this interest of yours come from? Was yours a musical family?
M: It wasn’t musical in the sense that Mozart’s father was a professional musician and Bach had brothers and sons who were musicians. But my mother and father both wanted to encourage me and my brother in music. He became a violinist while I was a pianist.
