subject of scholarly inquiry

In the wake of Sgt. Pepper , the underground and mainstream press widely publicised the Beatles as leaders of youth culture, as well as “lifestyle revolutionaries”. The album was the first major pop/rock LP to include its complete lyrics, which appeared on the back cover. Those lyrics were the subject of critical analysis; for instance, in late 1967 the album was the subject of a scholarly inquiry by American literary critic and professor of English Richard Poirier , who observed that his students were “listening to the group’s music with a degree of engagement that he, as a teacher of literature, could only envy”. The elaborate cover also attracted considerable interest and study. A collage designed by pop artists Peter Blake and Jann Haworth , it depicted the group as the fictional band referred to in the album’s title track standing in front of a crowd of famous people . The heavy moustaches worn by the group reflected the growing influence of the hippie movement, while cultural historian Jonathan Harris describes their “brightly coloured parodies of military uniforms” as a knowingly “anti-authoritarian and anti-establishment” display.
