Question: How many years after Wish You Were Here was released was The Wall released? 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: Did TJ Maxx make a profit the year Famous-Barr was re-branded as Macy's? Passage:Northpark Mall opened in 1972, on Range Line Road on the east side of Joplin. At the time, the mall was anchored by Montgomery Ward to the north, JCPenney to the south, and local chain Newman's the middle. Other stores included Walgreens, McCrory's, Ramsay's department store, For All Bible (which is still in business), Wyatts cafeteria, as well as many other stores. Newman's became Heer's in 1987, the same year that a new wing was built, and the mall received its first renovation. The new wing extended easterly from the JCPenney store. This new wing included two new anchors, Famous-Barr and Venture. The renovation also brought a food court as well as a new 5 screen cinema. In 1994, Heer's closed, and Famous-Barr moved its men's wear and home goods to the former Heer's space. That same year Sears built a store adjacent to Montgomery Ward, moving from an older store near downtown Joplin. In 1998 the mall received a minor renovation, changing only the color scheme. After the closure of the Venture chain in 1998, its anchor at the mall was converted to Shopko, but it closed in the early 2000s following the closure of Montgomery Ward in 2001. Both Famous-Barr locations were re-branded as Macy's in 2006. Montgomery Ward remained vacant until mid-2007, when its space was split between TJ Maxx and Steve & Barry's, the latter of which closed in 2008 and was replaced by Vintage Stock. In 2006 the mall received its first major renovation in nearly 20 years, changing the color scheme, adding all new lighting and floor tiles, and renovating the food court to a route 66 theme.

Question: What was the difference in age of the actor who performed under the stage name David Baron and his wife who appeared at the Connaught Theater during the same period? Passage:A temporary closure during World War II was followed by a period in which the theatre was managed on Seebold's behalf by a group associated with the J. Arthur Rank Organisation, who pursued a policy of employing young actors who later became important figures in film, television and theatre. Glenda Jackson, Susannah York, Charles Morgan, Maria Charles and several others appeared at the theatre during this period. In the 1950s, Alan Ayckbourn appeared in several plays at the Connaught. In 1956, Winston Churchill visited the theatre to see his daughter Sarah perform in Terence Rattigan's play Variation on a Theme. Harold Pinter acted at the Connaught under the stage name David Baron, moving to a house just a few yards from the theatre in Ambrose Place in the 1960s. Pinter's first wife, actress Vivien Merchant acted at the Connaught during this period. Giles Cooper worked with Pinter at the Connaught. Robin Maugham wrote several plays which he directed and premiered at the Connaught, including The Claimant (1962) and Winter in Ischia (1964). Actress Marina Sirtis, perhaps best known for her role on , began her career in repertory at the Connaught in 1976. Actor Robert Blythe has also worked in repertory theatre at the Connaught.
