Francis Douglas Arthur Keston (5 December 1924 – 13 February 2022), generally known as John Keston, was a British-born American stage actor and singer who was best known as a world record-breaking runner. Early life Keston was born in London on 5 December 1924. He served in the Royal Air Force during World War II. Artist Keston's best known acting performance may be his portrayal of Gehn, the complex villain from the video game Riven: The Sequel to Myst (1997). The character has developed a cult following. (A short scene in which Keston is heard singing "O Sole Mio" is hidden in the game, in a type of file known as an Easter egg. It was unscripted—filmed while Keston gave an impromptu performance when waiting between takes.) In 1968, John Keston appeared with Juliet Prowse in the original West End (London) production of Neil Simon's Sweet Charity at the Prince of Wales Theatre, in the role of Vittorio Vidal, receiving billing directly below the title. The show was conceived, staged and choreographed by Bob Fosse (who also made significant but uncredited contributions to the book). Keston appears on the cast album of that production. He once recalled his audition for Neil Simon, who was bringing the hit show to London from Broadway. Being a trained singer, Keston wanted to be taken seriously as an actor. When asked if he could sing, he said, "A bit." He was taken aside for his vocal audition, gave an excellent performance, and got the job. Charity was his only West End credit; he had previously appeared in London productions of Sleeping Beauty, House of Cards, The Ideal Husband, Private Lives, and Billy. He also toured in the revue Fol-De-Rols. British television appearances included Department S, Lord Byron, and U.F.O. For a time, Keston made a living as a model; his print ads appeared in such magazines as Stern. In 1974, Keston travelled to Washington, D.C. with the Royal Shakespeare Company's touring production of Sherlock Holmes, directed by Frank Dunlop, with artistic director Trevor Nunn. The company commenced its tour on 7 October at Kennedy Center's Eisenhower Theatre. A month later, the show began previews at Broadway's Broadhurst Theater, opened on 12 November, and ran 471 performances. It received four Tony nominations and two Tony awards. It gave Keston his sole Broadway credit for his performance as Sir Edward Leighton. (It was the eighth time
