Of course he can escape the publicity. He can write the cheque and make it conditional on anonymity.
True. Although to be honest ... as I said earlier .... I have a lot more time for celebrities who write out cheques (from their own accounts) publicly than celebrities who feed on endless TV appearances - getting credit for raising money for charity (from those of us who can hardly afford it) raising their own charity profile without making a dent in their own personal wealth. And to-boot - a lot of them even dodge their taxes! Not mentioning any names of course. And then they get honours from Mrs Queen!
I've made a conscious decision to not give a penny to CIN, Comic Relief or any such load of old bollocks hosted by fame-hungry celebrities. I just give money to beggars in the street and the Salvation Army ... they're more honest!
