Answer the question at the end by quoting:

The Famous Flames were an American rhythm and blues vocal group founded in Toccoa, Georgia, in 1953 by Bobby Byrd. James Brown began his career as a member of the Famous Flames, emerging as the lead singer by the time of their first professional recording, "Please, Please, Please", in 1956. On hit songs such as "Try Me", "Bewildered", "Think", "I Don't Mind", and "I'll Go Crazy", the Flames' smooth backing harmonies contrasted strikingly with Brown's raw, impassioned delivery, and their synchronized dance steps were a prominent feature of their live shows. Altogether, they performed on 12 songs that reached the Billboard R&B and pop charts, in addition to being featured on numerous albums, including the groundbreaking Live at the Apollo.
In 1964, James Brown and Bobby Byrd formed their own production company, Fair Deal, in an attempt to promote their recordings to a crossover audience. As a result, Brown signed a contract with Smash Records, a subsidiary of Mercury to distribute the records. After the release of "Out of Sight", however, King Records stopped Brown from releasing any more recordings since he had not obtained the label's consent. This resulted in Brown not releasing any recordings for a year. In 1965, King released Brown's "Papa's Got a Brand New Bag", which became Brown's first number 1 as a solo artist on the R&B charts, as well reaching the top 10 of the Billboard Hot 100. The song also provided one of the first glimpses into a new sound cultivated by Brown and the James Brown Band that would later be labeled as funk.  The group performed in Hollywood movies such as Ski Party and appearing twice on The Ed Sullivan Show in 1966 (where The Flames were uncredited). The group also began to perform overseas and became a major attraction. About their success outside America, Famous Flame Bobby Bennett said, in an 2012 interview with the Cleveland Plain Dealer; "We were drawing crowds everywhere we went," says Bennett. "Not just in America. We'd go to London or Paris and we couldn't even leave the hotel to go sightseeing because we were getting mobbed by people."  Brown's solo aspirations led to the further dissension in the group, who felt they weren't being compensated properly. Lloyd Stallworth left the Flames shortly after the group's first appearance on The Ed Sullivan Show in early 1966, leaving Brown, Byrd, and Bennett. Dissension continued to grow throughout 1966 and 1967, and in 1968 the rest of the members of the Famous Flames decided to go on with their own separate careers, and the group quietly disappeared. In 1968, King released the group's Live at the Apollo, Volume II but edited out the Famous Flames' introduction, since the group had left Brown by then. The 2003 CD re-release of the album corrected that by restoring The Famous Flames' name credit.

IN: Ambrose was born in Lovington, Illinois, to Rosepha Trippe Ambrose and Stephen Hedges Ambrose. His father was a physician who served in the U.S. Navy during World War II.

Ambrose was the lone historian featured in the 1973-74 ITV television series, The World at War, which detailed the history of World War II.  He served as the historical consultant for the movie Saving Private Ryan. Tom Hanks, who starred in the movie, said he "pored over D-Day" and Band of Brothers in researching his role. Hanks also credited Ambrose's books with providing extensive detail, particularly regarding D-Day landings.  The HBO mini-series, Band of Brothers (2001), for which he was an executive producer, helped sustain the fresh interest in World War II that had been stimulated by the 50th anniversary of D-Day in 1994 and the 60th anniversary in 2004. Ambrose served as executive producer for Price for Peace, a documentary concerning the war in the Pacific theater during World War II, and for Moments of Truth, a TV documentary containing interviews with World War II veterans.  In addition, Ambrose served as a commentator for Lewis & Clark: The Journey of the Corps of Discovery, a documentary by Ken Burns. He provided commentary in twenty made-for TV documentaries, covering diverse topics, such as World War II, Lewis & Clark, and America's prominence in the 20th century. He also appeared as a guest on numerous TV programs or stations, including The Charlie Rose Show, C-Span programming, CNN programming, NBC's Today Show, CNBC's Hardball, and various programming on The History Channel and the National Geographic Channel. Ambrose's association with National Geographic stemmed, in part, from his designation as an Explorer-in-Residence by the Society.  In addition to his academic work and publishing, Ambrose operated a historical tour business, acting as a tour guide to European locales of World War II. Also, he served on the board of directors for American Rivers and was a member of the Lewis and Clark Bicentennial Council.
