After the war, Allan Webb resumed his stage career with the role of Count Almaviva in the 1946 Sadler's Wells production of "The Marriage of Figaro". In 1947 he appeared in the original run of the Vivian Ellis musical "Bless the Bride", and made several further stage appearances in the following two years. During this time he had a brief affair with the actress Sydney Malcolm, for which Gibbons quickly forgave him. He left the theatre in 1949 to become a director of a book club specialising in special editions, and later bought a bookshop in the Archway district of London. His health failed in the late 1950s and in 1958 he was diagnosed with cancer of the liver. He died in July 1959 at Oakshott Avenue.
