A PENSIONER from one of the UK’s top choirs is walking 200 miles this month to raise money for two national charities.

70-year-old David Alder is a member of Beaconsfield's Rock Choir, the largest amateur and most popular contemporary choir in the UK which has scored two top 20 albums and has appeared on the One Show and Paul O'Grady show.

David, who lost both his bladder and prostate to cancer six years ago, left home on Sunday to hike across the Brecon Beacons and Clwydian Hills before singing with Rock Choir at the Liverpool Echo Arena later this month.

To mark his personal milestone of being clear of cancer for five years, David is stepping out to raise money for the charities Action on Bladder Cancer and Prostate Cancer UK.

He said: "I'm now 70 but as I am fit, I thought that I would mark the milestone 200 times by raising some money.

"Members are being really supportive and I know that the thought of singing with thousands of them at the Echo Arena Liverpool will keep me going!"

Beaconsfield Rock Choir leader Katy Seath said: "He always gives 100 per cent in our rehearsals and performances, so when he told me about his plans I wasn't at all surprised.

"It’s wonderful that he's doing something so amazing to help others affected by cancer."

David left his home in Chalfont St. Peter on Sunday for Chepstow. He will then trek the 177-mile Offa's Dyke Path from Chepstow to Prestatyn, en route to the Rock Choir concert which takes place on June 29.

Rock Choir dedicates hundreds of performances each year to raise money and awareness for charity.
