 When Lisa , Apu , and the McCartneys gather on the Kwik @-@ E @-@ Mart roof , Apu tells Lisa , " I learned long ago to tolerate others rather than forcing my beliefs on them . You know , you can influence people without <unk> them always . It 's like Paul 's song , ' Live and Let Live ' . " Paul corrects Apu and says the song 's title is actually " Live and Let Die " . In the same scene , Apu refers to himself as the " fifth Beatle " , and Linda alludes to a line in the Beatles ' 1969 song " Octopus 's Garden " . The McCartneys later ask Lisa if she would like to hear a song , and Apu sings part of " Sgt. Pepper 's Lonely Hearts Club Band " , to which the McCartneys snap along .
