The show won a BAFTA and Nicholas was also nominated for best comedy performance.  After the show ended, he returned to musical theatre and various other entertainment roles, including producing and directing.

Nicholas I (Russian: Николай I Павлович , "Nikolay I Pavlovich" ; 6 July [O.S. 25 June] 1796 – 2 March [O.S. 18 February] 1855 ) was the Emperor of Russia from 1825 until 1855.  He was also the King of Poland and Grand Duke of Finland.  He is best known as a political conservative whose reign was marked by geographical expansion, repression of dissent, economic stagnation, poor administrative policies, a corrupt bureaucracy, and frequent wars that culminated in Russia's defeat in the Crimean War of 1853–56.  His biographer Nicholas V. Riasanovsky says that Nicholas displayed determination, singleness of purpose, and an iron will, along with a powerful sense of duty and a dedication to very hard work.  He saw himself as a soldier—a junior officer totally consumed by spit and polish.  A handsome man, he was highly nervous and aggressive.  Trained as an engineer, he was a stickler for minute detail.  In his public persona, says Riasanovsky, "Nicholas I came to represent autocracy personified: infinitely majestic, determined and powerful, hard as stone, and relentless as fate."  His reign had an ideology called "Official Nationality" that was proclaimed officially in 1833.  It was a reactionary policy based on orthodoxy in religion, autocracy in government, and Russian nationalism.  He was the younger brother of his predecessor, Alexander I.  Nicholas inherited his brother's throne despite the failed Decembrist revolt against him and went on to become the most reactionary of all Russian leaders.  His aggressive foreign policy involved many expensive wars, having a disastrous effect on the empire's finances. James A. Nicholas (1921 – July 15, 2006) was an orthopedic surgeon and a pioneer in the treatment of athletic injuries who was best known for performing four knee operations that saved the career of Hall of Fame quarterback Joe Namath.

In 1973 he established the Nicholas Institute of Sports Medicine and Athletic Trauma at Lenox Hill Hospital in Manhattan, New York.  Nicholas was a long time member of Westchester Country Club.  He died of colon cancer at age 85. Nicholas Ray (born Raymond Nicholas Kienzle Jr., August 7, 1911 – June 16, 1979) was an American film director best known for the movie "Rebel Without a Cause." Harry Norris (12 June 1888 – 15 December 1966) was an Australian architect, one of the more prolific and successful in Melbourne in the interwar period, best known for his 1930s Art Deco commercial work in the Melbourne CBD.  His designs were informed by his regular overseas trips, especially to the United States, which he visited at least every 18 months from perhaps the late 1920s; and he was one of the very first architects to introduce Art Deco style buildings to central Melbourne.  He had a strong relationship with the wealthy Nicholas family, designing not only the Nicholas Building, but the simpler yet similar Nicholas Factory in South Melbourne, and the spectacular mansion 'Burnham Beeches' in the Dandenongs for Alfred Nicholas.  He also had a long relationship with G J Coles, designing branches of their eponymous Coles Stores from the late 1920s, numerous matching Art Deco branches in the 1930s, and some of their earliest supermarkets in the 1950s, as well as a country house for E.B.Coles in 1938.  He refused membership of the RVIA for many years until finally joining on the 21 February 1946.  Harry Norris retired on his 76th birthday in June 1966 and died 6 months later. Nicholas W.
