He said: “It was great to have the support of Ian and Rory at the concert and to be able to discuss Christmas Crackers with them.
“I also took the opportunity to show them the brilliant illustrations by Oxford artist Korky Paul and cartoonist Gerald Scarfe which have really helped to bring the book to life.”
“I’ve been overwhelmed by the response to the book from people all over the UK.
“It’s wonderful to have raised such an amount for Parkinson’s research.”
Director of fundraising at Parkinson’s UK Paul Jackson-Clark said: “I’d like to say thank you to John for donating the proceeds of his popular book to research into Parkinson’s.
“There are a lot of exciting studies happening in Oxford which we are pleased to fund, but this wouldn’t be possible without the determination of fundraisers like John.
“I hope even more people decide to add this book to a Christmas stocking this year.”
