 When asked about the development of the song , Martin said : " My father @-@ in @-@ law Bruce Paltrow bought this big keyboard just before he died . No one had ever plugged it in . I plugged it in , and there was this incredible sound I 'd never heard before . All these songs poured out from this one sound . Something has to inspire you , and something else takes over . It 's very cloudy . " Martin also noted that the song is " probably the most important song we 've ever written " .
