Question: Which man, Nigel Clark or Ben Jorgensen, is an American musician?
Context: Unclaimed is a 2013 Canadian documentary film about a man who claims to be former Special Forces Green Beret Master Sgt. John Hartley Robertson, who was declared dead after being shot down over Laos on a classified mission on 20 May 1968.  The documentary is written, directed, and produced by Michael Jorgensen.  It follows Tom Faunce, a veteran of the Vietnam War, in tracking down the man who claimed to be Robertson.  Faunce was skeptical of Robertson's identity but eventually became convinced.  He convinced Jorgensen to make a documentary about Robertson's story as a way to unite the man with his American family. Nigel Clark (born 25 March 1956) is a British modern pentathlete.  He competed at the 1980 Summer Olympics where he finished 8th in the team event and 33nd in the individual event. Nigel Richard Clark (born 18 September 1966 in Redditch, Worcestershire) is an English singer-songwriter, best known as the lead singer and bassist of Dodgy. What to Do When You Are Dead is the second studio album by American rock band Armor for Sleep.  Following the completion of two songs written from the perspective of being dead, vocalist/guitarist Ben Jorgensen created a whole story from this perspective.  "What to Do When You Are Dead" is a concept album, with each song telling the story of the protagonist's suicide as well as his journey through the afterlife.  Recording took place between August and October 2004 with producer Machine.  A rough mix of "Car Underwater" was made available in November, followed by two US tours in February 2005.  "What to Do When You Are Dead" was released on February 22 through independent label Equal Vision Records. Don Clark (born May 30, 1975) is an American musician.  He was the rhythm guitarist and bassist for the Christian metal band, Demon Hunter, which he co-founded with his brother, vocalist Ryan Clark.  Before Demon Hunter, Clark was a former guitarist and co-founder of Training for Utopia with Rob Dennler.  He appears on Zao's "The Lesser Lights of Heaven" DVD. Burning Love and Hits From His Movies, Volume 2 is a compilation album by American singer and musician Elvis Presley.  The album was released on November 1, 1972 on RCA's budget label, RCA Camden.  The contents of the album consist primarily of soundtrack recordings from various Presley films of the 1960s, augmented by both sides of his 1972 hit single, "Burning Love".  This was considered unusual as according to Presley discographer Ernst Jorgensen in his book "A Life in Music", RCA generally reserved hit singles for release on the main RCA Victor label, and not the budget Camden spin-off.  RCA repeated the experiment a month later with the release of the compilation "Separate Ways" which similarly featured a hit single leading a collection of non-hit soundtrack recordings.  Upon its release, it reached number 22 on the Billboard chart.  It was certified Gold on March 27, 1992, Platinum on July 15, 1999 and 2x Platinum on January 6, 2004 by the RIAA.
