YIKES! HUSBAND (FRANK FINLAY) falls for daughter (SUSAN PENHALIGON) while wife (SHEILA ALLEN) is busy bedding son-in-law (JAMES AUBREY). All manner of kinkiness in caravans followed, lapped up by a nation of Sunday night stickybeak curtain-twitchers. Airy theme tune sounded like it belonged in a porn film. Minuscule number of shabby-looking sets and cast’s penchant for lugubrious stares into the middle distance didn’t matter when at the hands and feet (and everything in between) of such estimable faces. You couldn’t help but tune in, because you thought everybody else was.
