Another video clip dating a few years back, but interesting in its contents. The two-seater Grace Spitfire, ML407, has a dedicated group of  supporters who help keep the aircraft flying. This group also meets once a year for an annual gathering. This video documents the 2005 event in Duxford, with Carolyn Grace flying the aircraft.

ML407 has a very long history including claiming the first enemy aircraft on D-Day when flown by Johnnie Houlton. You can find out more at the official Grace Spitfire site.
