Some of the 1970s had styles that were in monumental bad taste. It was if the culture of the 1960s was warped in the new decade. Polyester clothing, hailed as a breakthrough since it needed no ironing, was one abomination. Leisure suits were ghastly in their double-knittedness. Farah Fawcett hair on white women, enormous block-the-movie-screen Afros on women. Embarassing blaxploitation films, spin-offs from the pretty good groundbreaking film "Shaft." There were so many black copies of other films' themes ("The Black Godfather"), that one black film critic I had the honor of hearing at a Telluride film festival said he expected there to be a black "Jaws." I am proud that "Saturday Night Fever" was filmed and about my old Brooklyn neighborhood, but what it did for music was awful. There were so many "disco versions" of older songs, I fully expected there to appear a disco version of Ave Maria.
As the decade ended, disco died an ignominious death in Chicago's Comisky park.
On this day in 1979, a fun MLB promotional event quickly devolved into the most infamous and controversial event in disco history.

On the other hand, the decade redeemed itself for us who appreciate feminine pulchritude by popularizing the somewhat tacky but eminently noticeable slit skirt, a fashion statement previously associated with ladies of the night.
