 As a result of the Falklands War , Waters changed direction and wrote new material . He saw British Prime Minister Margaret Thatcher 's response to Argentina 's invasion of the islands as jingoistic and unnecessary , and dedicated the new album — provisionally titled Requiem for a Post @-@ War Dream — to his father , Eric Fletcher Waters . A second lieutenant of the 8th Royal Fusiliers , Eric Waters died during the Second World War at Aprilia in Italy , on 18 February 1944 . Gilmour was unimpressed by Waters ' apparent politicising and the new creative direction prompted arguments between the two . Several pieces of music considered for but not used on The Wall , including " Your Possible Pasts " , " One of the Few " , " The Final Cut " and " The Hero 's Return " , had initially been set aside for Spare Bricks , and although Pink Floyd had often re @-@ used older material in their work , Gilmour felt the songs were not good enough for a new album . He wanted to write new material , but Waters remained doubtful as Gilmour had lately contributed little to the band 's repertoire .
