Given the question: Read the following paragraph and extract the answer for the question: What is the last name of the person that the band that released an album in 1983 did not choose to use for the cover design?  In 1982, Waters suggested a new musical project with the working title Spare Bricks, originally conceived as the soundtrack album for Pink Floyd – The Wall. With the onset of the Falklands War, Waters changed direction and began writing new material. He saw Margaret Thatcher's response to the invasion of the Falklands as jingoistic and unnecessary, and dedicated the album to his late father. Immediately arguments arose between Waters and Gilmour, who felt that the album should include all new material, rather than recycle songs passed over for The Wall. Waters felt that Gilmour had contributed little to the band's lyrical repertoire. Michael Kamen, a contributor to the orchestral arrangements of The Wall, mediated between the two, also performing the role traditionally occupied by the then-absent Wright. The tension within the band grew. Waters and Gilmour worked independently; however, Gilmour began to feel the strain, sometimes barely maintaining his composure. After a final confrontation, Gilmour's name disappeared from the credit list, reflecting what Waters felt was his lack of songwriting contributions.Though Mason's musical contributions were minimal, he stayed busy recording sound effects for an experimental Holophonic system to be used on the album. With marital problems of his own, he remained a distant figure. Pink Floyd did not use Thorgerson for the cover design, Waters choosing to design the cover himself. Released in March 1983, The Final Cut went straight to number one in the UK and number six in the US. Waters wrote all the lyrics, as well as all the music on the album. Gilmour did not have any material ready for the album and asked Waters to delay the recording until he could write some songs, but Waters refused. Gilmour later commented: "I'm certainly guilty at times of being lazy ... but he wasn't right about wanting to put some duff tracks on The Final Cut." Rolling Stone magazine gave the album five stars, with Kurt Loder calling it "a superlative achievement ... art rock's crowning...
The answer is:
Thorgerson
