They asked Harry to help recreate the 1908 London Olympics originally held at White City, London.
The event was run by the Hammersmith & Fulham council in partnership with Queens Park Rangers Football club.
The format of the event was an interactive guided historical walk around London's White City ending inside the Queens Park Rangers football stadium.
The visitors meet William Leushner (played by Harry) the American Olympic 1908 shooting champion and the British Gold 400m medalist WyndhamHalswelle.
They have since developed these roles to be able to offer a staged scenario which not only encompass some of the period games but also the politics of the 1908 Olympic games.
During 1908 London Olympics numerous complaints and disputes occurred between the British and American competitors.
Harry & Edna portray this with a light hearted conversation between Leushner and a female official from
Leushner complains his accommodation for the games was in Brighton and even though Halswelle ran the 400m as the sole competitor, he still came last or in the games officials view Halswelle came 1st, 2nd and 3rd.
