British video essayist Film Retrospective gave a meticulous accounting of how The Beatles recorded the much-awaited 1967 album Sgt. Pepper’s Lonely Hearts Club Band. It was a tumultuous time for them. George had quit the band after the show at Candlestick Park in San Francisco but rejoined after they promised to quit touring.
