Knees Up Mother Brown
(Concord Films Council short film, 1964)
Includes footage of a 'Darby and Joan' coach trip to Southend aboard two coaches of Leighton of Ilford. Both are seen only from behind. Definitely identifiable is 7696HP, a 1960 Ford 570E/Duple Yeoman. The other I believe is 303PHK, their 1959 Commer Avenger IV/Duple Corinthian, but we never see the registration.
