Question: How many years after Thorgerson designed the cover with the man on fire for Pink Floyd did he pass away? Passage:Storm Thorgerson, who had done the majority of album covers for Pink Floyd, did the Echoes art which features recursive windows in an infinite regression as a nod to his own cover for 1969's Ummagumma, and the objects on each landscape refer to the Pink Floyd discography. For instance, there's the man on fire from Wish You Were Here, another wearing the Delicate Sound of Thunder lightbulb suit, dolls of the Atom Heart Mother cow and the Animals pig, a bike and both a brick wall and the hammers from The Wall. Eventually Thorgerson opted to make two images, with another used for the back cover. To create the idea on a photograph, various walls - which had varied measurements and angles to ensure that "nothing seemed to fit other than by eye through the lens." - were built and put in a country landscape in Sussex. Actors, props and fittings were set in and between those walls. The original design was one of two sketches submitted for Dream Theater's 1997 album Falling into Infinity, with the original being framed and hanging in the home of former Dream Theater drummer Mike Portnoy and is pointed out by Portnoy in his Hudson Music instructional drum DVD In Constant Motion.

Question: Was Don Cornelius alive at the time Townsend wrote Hollywood Shuffle? Passage:In 1987, Townsend wrote, directed and produced Hollywood Shuffle, a satire based on the hardships and obstacles that black actors undergo in the film industry. The success of his first project helped him establish himself in the industry. Another of his films was The Five Heartbeats based on 1960s R&B male groups and the tribulations of the music industry. Townsend created and produced two television variety shows—the CableACE award–winning Robert Townsend and His Partners in Crime for HBO, and the Fox Television variety show Townsend Television (1993). He also created and starred in the WB Network's sitcom The Parent 'Hood which originally ran from January 1995 to July 1999. In 2018, Townsend also directed 2 episodes for the B.E.T. Series American Soul which began airing in 2019. The show is about Don Cornelius and Soul Train. Townsend was programming director at the Black Family Channel, but the network folded in 2007. Townsend created The Robert Townsend Foundation, a nonprofit organization whose mission is to introduce and help new unsigned filmmakers.

Question: How long was the war in which Netterville's estates were sequestered? Passage:Viscount Netterville was a title in the Peerage of Ireland. It was created in 1622 for Nicholas Netterville, 1st Viscount Netterville (1581–1654), son of John Netterville of Dowth, County Meath. He was a favorite of King James I of England who in 1622 conferred the title on him "in consideration of his many good qualities". He suffered considerable financial hardship during the English Civil War when the English Parliament, after the failure of the Royalist cause, sequestered his estates, along with those of his eldest son, John, the 2nd Viscount. During the Irish Rebellion of 1641 John, who was adhered to Roman Catholicism, was accused of favouring the rebels, and it does not seem that either side to the conflict fully trusted him. Possibly for this reason his son Nicholas, the 3rd Viscount, had some difficulty after the Restoration of Charles II in recovering the family estates. Because of Nicholas's loyalty to James II the estates were again forfeited after the Glorious Revolution of 1688, but were later restored to his son John, the 4th Viscount.
