Paul McCartney "shouted out" to several of his relatives and friends in this song: his aunt ("Auntie Gin") and brother ("Brother Michael"), the Everly Brothers ("Phil and Don"), Keith Moon ("Uncle Ernie") and his famous former bandmate ("Brother John"). His reference to "Sister Suzie" was a reference to Linda, who once recorded a song under the name "Suzie And The Red Stripes."
Paul McCartney told The Mail on Sunday
magazine: "When we went to Jamaica on holiday, a lot of the local guys used to call Linda 'Susie' for some reason. And we kind of liked that. Then 'brother John' – I would be thinking either of John Lennon, or Linda's brother, John. But the weirdest thing is, my wife now, Nancy, has a sister Susie and a brother John."
