Question: Question: When was Zimbabwe's new flag first raised? Passage:Following Rhodesia's Unilateral Declaration of Independence from the British Empire, the new Rhodesian authorities started to crack down on African liberation movements. One of their considerations was to ban performance of "Ishe Komborera Africa" in African schools and public performance of it often made people liable for arrest by the British South African Police. The District Commissioner for Gutu abolished the Gutu African Council after its leader opened a meeting by singing "Ishe Komborera Africa" in the District Commissioner's presence. The Commissioner also had the leader arrested but he was released without charge. Following the Southern Rhodesian general election, 1980, after Zimbabwe Rhodesia returned to British control as Southern Rhodesia, Robert Mugabe's Zimbabwe African National Union party won to become the first government of an independent Zimbabwe. After this, "Ishe Komborera Africa" was selected to replace the official "God Save the Queen" of Southern Rhodesia and the unofficial "Rise, O Voices of Rhodesia" of Rhodesia as the national anthem of an independent Zimbabwe as it was a symbol of black African struggles and solidarity against apartheid systems in South Africa and Namibia. At the Zimbabwean independence ceremony, the Union Jack was lowered to "God Save the Queen" and the new flag of Zimbabwe was raised to "Ishe Komborera Africa" in Salisbury.

Question: 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.
