Looking back now at my first World Cup experience, I didn't know what was going on. I was a newbie and I had no idea what to expect.
The expectation on me as a solo artist is very different to the audience's expectation of a Pink Floyd show.
I try to get them working. My older son is 10 and he's pretty interested. We had a dinner party the other night and he helped a lot. He helped peel asparagus; he hung out. It was great.
