As a cameraman, I was paid to stand within a few feet of Yehudi Menuhin performing. I saw Rudolph Nureyev dancing. I couldn't believe I was being paid for that.
I worked on 'Blue Peter' and 'Tonight' and lots of TV plays, filmed people like Rudolf Nureyev and Ted Heath, and ended up a senior cameraman with my own crew.
