John Arthur Alexander Edgecombe (22 October 1932 – 26 September 2010) was a British jazz promoter, whose involvement with Christine Keeler inadvertently alerted authorities to the Profumo affair.
Searching for his missing father, he hid on a ship bound for Texas, but on arrival was arrested and put back on board for the return trip.
On 14 December 1962, Edgecombe took a taxi to the Marylebone home of osteopath Stephen Ward, where Keeler was in hiding along with friend Mandy Rice-Davies.
In 1987, he made an extended appearance on an edition of the live television discussion programme After Dark alongside Tony Blackburn, Peter Tatchell, Victoria Gillick and others.
Edgecombe also appeared briefly in the 1989 TV documentary The Scandal Story where he described and reenacted the shooting incident outside the actual Marylebone house.
