The advance single features Taylor-Joy ( The Witch) doing a soulful cover of Petula Clark’s classic “Downtown.” It evokes the uneasy wonderland of the ghosts of the past. The movie moves to the rhythm of the background songs, which become a character. The soundtrack seeks to evoke two eras, the sounds of 1965 Soho and present-day London, while keeping time for the film. The soundtrack to the film is the aural equivalent of a middle-eight between the verses and the chorus of time. The singer, Sandie ( Anya Taylor-Joy), is the most lucid bridge to her subconscious trespass. But in her dreams she is a mid-‘60s Mod, shaking to the sounds of Swinging London. Eloise (Thomasin McKenzie) is a modern fashion design student in the film-modern in the sense that she is a 21st century woman living in contemporary England. Like a needle on a record, Edgar Wright’s Last Night in Soho drops a sharp stylus into a deep groove and lets her spin.
