Michael’s Bradshaw’s-inspired rail tour of London continues in Hampstead, where shortly before the outbreak of the Second World War, a groundbreaking Jewish doctor found refuge. Sigmund Freud fled the Austrian capital of Vienna by train to escape the Nazis, who branded his work degenerate. Michael hears how the father of psychoanalysis was warmly welcomed in London and sees the famous couch, upon which patients would lie to recount their dreams. In St John’s Wood, Michael discovers how Britain went on record between the wars at the Abbey Road Studios. He is amazed by the cavernous space in which Sir Edward Elgar and the London Symphony Orchestra played at the grand opening ceremony in 1931, and he's awed by the list of famous names to follow their lead, topped by the Beatles, who immortalised Abbey Road on an album cover. A young violinist brings Studio 2 to life with a tribute to Elgar.
