Saturday Night Fever is one of those bona fide classics. The film starring John Travolta was a gritty depiction of working class life in the Bay Ridge suburbs of the Bronx set to a genre defining soundtrack. That musical backbeat to the tribulations of Tony Manero formed the cornerstone of the phenomenon that would become disco. The stage version, currently on tour at Manchester Palace, therefore was a must see event for all those lovers of glitter balls, iconic white suits and some killer dance moves that Wigan Casino veterans would no doubt remember in their heyday.
