Nice little earner?

Although I no longer do, I used to go to a local primary school once a week and play the piano for a kids' sing-song. As there were always teachers present, I did not have to be vetted in any way. This seemed sensible. But now apparently, as from October, if I were still doing it, I would not only have to be fully vetted, but would have to pay £64 for the privilege! We seem to have lost our sense of proportion. Several authors of children's books who go into schools to read to them are up in arms about it, and I'm not surprised. Apparently some five million people will be affected. Now let me see - five million times £64....or am I just being cynical?
