The more I read, the more I think he is the Magister Ludens.
From a profile in sunday’s Observer:
Now 75, he is able to say: ‘I know who I am and what I like to do, and all I ever wanted was to splosh around with my brushes and palette and show people that painting can be fun. My advice is to just do something you love to do.
‘You need to do something that means you wake up with a smile on your face, and look in the mirror and say, “I really love you, son. Good on ya. Get on with it!” I just feel about 20, still.’
Oh, and George – he’s Welsh-born.

And we laughed when we told the naive Las Vegas art students that Tony Hart, Neil Buchanan and Rolf Harris were the new up and comming artists to look out for…
From the Guardian article: “Harris was born in western Australia in 1930 to Welsh emigre parents, Crom and Marge Harris, and remembers wanting to be a painter from an early age.” So I suppose he’s not Welsh-born but is fairly claimed as Welsh. Cool guy; he was big on Canadian TV too.
Sanjay rocks.
Bloody Welsh. They’re like vacuums.
