Lambeth Walk is the film version of the evergreen West End musical Me and My Girl, which was still being successfully revived into the 1980s. The enormously popular music-hall entertainer Lupino Lane repeats his stage characterization as Bill, a diffident working-class cockney who finds himself heir to a title and a vast estate. Though he now has his pick of England's most gorgeous debutantes, Bill remains faithful to his blue-collar girlfriend Sally (Sally Gray). (allmovie.com)
