The Beatles‘ “Your Mother Should Know” was inspired by Paul McCartney’s interactions with his aunt. In addition, it was supposed to advocate peace between generations. Notably, its message was really out of step with the 1960s counterculture.
In the 1997 book Paul McCartney: Many Years From Now, Paul discussed the origin of “Your Mother Should Know.” “My Aunty Jin and Uncle Harry and a couple of relatives were staying and they were in the living room just across the hall, so I just went to the dining room and spent a few hours with the door open with them listening,” he recalled.
This environment inspired him to write “Your Mother Should Know.” He felt the song was “basic.” Paul felt he probably wouldn’t have written it if Aunty Jin wasn’t nearby.
