This battle began after Sinead O’Connor threatened not to perform at a New Jersey concert venue during her “I Do Not Want What I Haven’t Got” tour, because she didn’t want to sing the national anthem as requested by the venue.
According to the LA Times, the singer said she “has a policy of not having national anthems played before my concerts in any country, including my own, because they have nothing to do with music in general.”
The next night after her performance, Frank Sinatra took the same stage and told his audience, “I’d like to kick her in the a–!”
She later told Esquire Magazine in 1991: “I can’t hit this man back, he’s like 78 years of age, and I’d probably kill him.”
