It's not so much the song as it is a Judy Garland thing. Watching the Wizard of Oz on the big screen at the Fox Theater in Atlanta is a special treat. The majority of the audience is gay. They sing ALL the songs and hisssssssss every time the witch comes on the screen.
I did the same at the Ford Oriental Theatre in Chicago. I know about the Judy Garland “thing,” but it was more of a family event. They handed out props to the kids, it was a lot of fun.
