Yes, someone got to him around then.
Pre 1990 he was doing homosexual updates, to "Back in the Saddle, Again" bumper tune.
Then he did a TV show, substituting for Pat Sajek; audience occupied by gays. He had to remove the audience to complete the show.
So much for free speech.
Rush has not talked about it since.
Someone got to him.
He still lampoons Barney Frank with “Banking Queen” and “Lollipop” and has a spoof of Frank on his regular rotation of commericals for the online audience.
All of these are attacks on Frank’s gay lifestyle as well as his politics.
