Way back when I was a kid, my sister had the film soundtrack album. My big brother thought the original was an outrage because New York toughs were dancing around like a bunch of pansies. Later I witnessed the June 1973 Stonewall Inn commemorative parade and was shocked that there really were endless perverted sissies from tough Westside, Bowery, and Bronx neighborhoods.
It’s a musical. Operas have soldiers singing while they are killing each other.
