<P> Flanagan and Allen's songs featured the same, usually gentle humour for which the duo were known in their live performances, and during the Second World War reflected the experiences of ordinary people during wartime . Songs like "We're Going to Hang Out the Washing on the Siegfried Line" mocked the German defences (Siegfried Line), while others like "Miss You" sang of missing one's sweetheart during enforced absences . Other songs such as their most famous "Underneath the Arches" (which Flanagan co-wrote with Reg Connelly) had universal themes such as friendship, which, again, helped people relate to the subject matter . The music was usually melodic, following a binary verse, verse chorus structure, with a small dance band or orchestra providing the backing . The vocals were distinctive because, while Flanagan was at least a competent singer and sang the melody lines, Allen used an almost spoken delivery to provide the harmonies . </P> <P> Allen semi-retired in 1945 and Flanagan increasingly became a solo performer, although the two of them still appeared together on occasion, including for the 1957 TV series Together Again . In 1959 Flanagan was awarded the OBE, and received the award from the Duke of Edinburgh at Buckingham Palace . By the 1960s, and with his popularity on the wane, Flanagan used his wealth to invest in betting shops . Flanagan was a member of the Entertainment Charitable fraternity, the Grand Order of Water Rats . </P> <P> Flanagan's last recording was Jimmy Perry and Derek Taverner's theme for the British sitcom Dad's Army, "Who Do You Think You Are Kidding, Mr Hitler?", recorded by Pye shortly before his death in 1968 and for which he was paid 100 guineas (£ 105). The song was a pastiche of the sort of songs Flanagan had sung during the war . </P> <P> Flanagan was cremated at the Golders Green Crematorium . </P>
