David Wiffen (born March 11, 1942 in Sydenham, London, England) is a Canadian folk music singer-songwriter. Two of his songs, "Driving Wheel" and "More Often Than Not", have become cover standards. Brought up in South London and Claygate, Surrey, Wiffen first sang with the Kingston upon Thames-based Black Cat Skiffle group. Wiffen moved with his family to Canada at age 16, and became part of the burgeoning folk music scene, initially in Toronto. In 1965, having moved to Vancouver, he was invited to perform at The Bunkhouse club on a live ensemble album.
