Problem: Vladimir Vladimirovich Nabokov (; Russian: Vladimir Vladimirovich Nabokov, pronounced [vla'djimjIr na'bok@f] ( listen), also known by the pen name Vladimir Sirin; 22 April [O.S. 10 April] 1899 - 2 July 1977) was a Russian-American novelist, translator and entomologist.

Nabokov was a classical liberal, in the tradition of his father, a liberal statesman who served in the Provisional Government following the February Revolution of 1917. Nabokov was a self-proclaimed "White Russian", and was, from its inception, a strong opponent of the Soviet government that came to power following the Bolshevik Revolution of October 1917. In a poem he wrote as a teenager in 1917, he described Lenin's Bolsheviks as "grey rag-tag people".  Throughout his life, Nabokov would remain committed to the classical liberal political philosophy of his father, and equally opposed Tsarist autocracy, communism and fascism.  Nabokov's father Vladimir Dmitrievich Nabokov was the most outspoken defender of Jewish rights in the Russian Empire, continuing in a family tradition that had been led by his own father, Dmitry Nabokov, who as Justice Minister under Tsar Alexander II had successfully blocked anti-semitic measures from being passed by the Interior Minister. That family strain would continue in Vladimir Nabokov, who fiercely denounced anti-semitism in his writings, and in the 1930s Nabokov was able to escape Hitler's Germany only with the help of Russian Jewish emigres who still had grateful memories of his family's defense of Jews in Tsarist times.  When asked, in 1969, whether he would like to revisit the land he had fled in 1918, now the Soviet Union, he replied: "There's nothing to look at. New tenement houses and old churches do not interest me. The hotels there are terrible. I detest the Soviet theater. Any palace in Italy is superior to the repainted abodes of the Tsars. The village huts in the forbidden hinterland are as dismally poor as ever, and the wretched peasant flogs his wretched cart horse with the same wretched zest. As to my special northern landscape and the haunts of my childhood - well, I would not wish to contaminate their images preserved in my mind."

Where was he when the revolution occurred?

Background: The Ink Spots were an American pop vocal group who gained international fame in the 1930s and 1940s. Their unique musical style led to the rhythm and blues and rock and roll musical genres, and the subgenre doo-wop. The Ink Spots were widely accepted in both the white and black communities, largely due to the ballad style introduced to the group by lead singer Bill Kenny. In 1989, the Ink Spots (Bill Kenny, Deek Watson, Charlie Fuqua and Hoppy Jones) were inducted into the Rock and Roll Hall of Fame, and in 1999 they were inducted into the Vocal Group Hall of Fame.
Context: In 1943, Ink Spots baritone singer and guitarist Charlie Fuqua was drafted into the US Army. He chose his friend Bernie Mackey to be his temporary replacement until he returned to the group. After being with the group for two years, Mackey was replaced by Huey Long in March 1945. Long completed the role as a "fill in" until Fuqua finally returned in October 1945.  Hoppy Jones, an important personality to the group, died in October 1944, after collapsing on stage at the Cafe Zanzibar in New York City, near the height of their popularity. Hoppy Jones had been having cerebral hemorrhages for a year, and had fallen ill from it in June 1944. Jones was temporarily replaced by Cliff Givens who filled in for five months, from October 1944 to March 1945. Jones' permanent replacement was to be Bill Kenny's brother (and fraternal twin) Herb Kenny. Herb Kenny sang with the group from 1945 to 1951 when he went out for a career as a solo artist. The last bass singer for the Ink Spots was Adriel McDonald who was with the group from 1951 to 1954. McDonald was previously the Ink Spots' personal valet, a job given to him by Herb Kenny with whom he had sung in a group called "The Cabineers" in the early 40's.  Due to personality clashes between Bill Kenny and Deek Watson after Hoppy Jones' death, Kenny decided he'd rather carry on as the leader of the group and bought Watson's share of the group for $10,000, which in turn gave Kenny the power to kick Watson out of the group. Watson went on to form a group similar in style to the Ink Spots called the Brown Dots (which later became the Four Tunes). Watson's place was filled by Billy "Butterball" Bowen who sang with the group from 1943 to 1952.
Question: Did he come back to the group after he left the army ?
Answer: Mackey was replaced by Huey Long in March 1945. Long completed the role as a "fill in" until Fuqua finally returned in October 1945.

Question:
Barclay was born in Chicago Heights, Illinois. He attended La Lumiere School, a private college preparatory boarding school in La Porte, Indiana. On scholarship, he was one of the first African-Americans to attend the school, Barclay went on to Harvard College, where he was extremely active in student musical theatre productions and the a cappella singing group The Harvard Krokodiloes.
Following his graduation from Harvard, he worked as a copywriter and creative supervisor at Grey, BBDO, Cunningham & Walsh, and Marsteller. Barclay then moved into music video directing and production through his own company, Black & White Television. He directed music videos for Bob Dylan ("It's Unbelievable"), the New Kids On The Block ("Games" ), Janet Jackson and Luther Vandross ("The Best Things in Life Are Free" ). Most notably, he created eight videos for LL Cool J, including "Mama Said Knock You Out", which won awards from both MTV and Billboard--and went on to be listed by The Rock and Roll Hall of Fame as one of the 500 songs that shaped rock and roll. In 2013, Complex Magazine ranked "Mama Said Knock You Out" as one of the top 50 rap videos of the 1990s, crediting it with creating "one of the most crucial links in establishing the cultural bridge between boxing and rap." Barclay was often hired to direct videos for films, introducing audiences to House Party (1990), White Men Can't Jump (1992), Mo' Money (1992), Posse (1993), and Cool Runnings (1993), among others.  In 2012, Barclay directed his first music video in 16 years, working once again with LL Cool J and R&B star Joe on the video for "Take It".  Also drawing on his music video experience was Barclay's episode ("The Coup") of the Steven Spielberg-produced NBC series Smash, in which TV Fanatic said that the Barclay-directed number for the original song "Touch Me" (written by OneRepublic's Ryan Tedder) "pushed the boundaries from traditional Broadway show to music video level."
