TV Picks of the Week: The Joy Of Disco, Modern Family, Six Nations Rugby

Young man, there’s no need to feel down! And after seeing Saturday Night Fever for the first time this one left the cinema in early 1978 with a spring in his step.

Replicating John Travolta’s walk in the opening credits – that Brooklyn bounce, paintpot in hand – was tougher despite loyalty-card membership of Annabel’s, Edinburgh’s Studio 53 and a half and a hop of Charlie-scented mystique lacking only a lit floor. This documentary should bring those mirrorball memories flooding back because the gang’s all here: Sister Sledge, Sylvester (whose Mighty Real was Annabel’s top stomper), the Bee Gees, the mighty Chic and, yes, the Village People. Cowboy Randy, still sporting his stetson, saw disco as nothing short of revolution: “We thought we were going up this hill towards a shining city at the top.”

BEST COMEDY Modern Family Sky1, Friday, 8pm
