I met him a couple of times, as he used to live In Cookham, Berks, and frequented the local butcher's where I did a lot of work.
At Christmas time, the butcher would ask all the local celebrities (there are a lot around there) to 'appear' in his shop as a PR thing. I was always in the shop around Xmas as there was always at least one fridge or coldroom breaking down.
I got talking to him once about cars and he told me about the day he was stuck on the M25 trying to get to the M4 junction which was the inspiration for 'road to hell'.
He was a really nice, normal, down-to-earth chap.
'Driving home for Christmas' is my 19 year old daughter's favourite Xmas song too.
