When George Bernard Shaw first tried to show his play Mrs Warren's Profession in the late 1890s, the Lord Chamberlain banned it because of its content - prostitution. The first production was in 1902 in a London members only club....there was no public performance in England until 1925! Mrs Warren's Profession's notoriety has faded, but the themes Shaw explored - women being underpaid and under-valued - certainly haven't.
