Olivia Newton-John: one of the first singer to push the boundaries before Mandonna.
I've seen many Mandonna fans all over the internet, claiming that Madonna was the first person ever to break the rules and talk about sex or gays in media. That is a lie, like almost everything they say. Olivia Newton-John was one of the artists who did it before Madonna. In her song 'physical' from 1981 she's singing about sexuality and put gay motives in a music video. That was a tabu subject in the 80's but Olivia braved to sing about that. This idea was lifted by Madonna 2 years later, which you can hear in 'physical attraction'.
