Here's Robert Hazard's "Girls Just Wanna Have Fun" from 1979, four years before Cyndi Lauper's cover

Musician Robert Hazard (1948-2008) wrote and recorded "Girls Just Wanna Have Fun" on a demo tape in 1979. Four years later, Cyndi Lauper covered it and it made her famous.

From Wikipedia:

The song was written by Robert Hazard, who recorded only a demo of it in 1979. Hazard's version was written from a male point of view. Lauper's version appeared on her 1983 debut solo record, She's So Unusual. The track is a synthesizer-backed anthem, from a feminist point of view, conveying the point that all women really want is to have the same experiences that men can. Gillian G. Gaar, author of She's a Rebel: The History of Women in Rock & Roll (2002), described the single and corresponding video as a "strong feminist statement", an "anthem of female solidarity" and a "playful romp celebrating female camaraderie."
