Derek was one of the main, if not the main, driving force behind the joining together of Sevenoaks Vine Cricket Club and Sevenoaks Hockey Club. The union was agreed in an extraordinary general meeting in July 1973 (K.J. Smart. Cricket on the Vine 1734-1894) and Derek became the first Chairman of the Sevenoaks Vine Club.
Derek played 1st and 2nd team cricket for the Vine as an all-rounder of quite some ability who could open the bowling or come on first change and bat 3 or 4.
