Moore's career spanned decades and included teaching himself to play guitar, writing the lyrics to 1,000 original songs, forming multiple bands, and even starring in a few film roles.
Moore's bands performed at well-known Los Angeles clubs, including Whisky a Go Go, The Troubadour, and Starwood, and headlined alongside The Police, The Knack, and The Motels.
Moore was born in Minneapolis, Minnesota, and aside from his family's brief move to San Francisco, California in 1966/67, grew up in the Twin Cities area.
Fearful that he would be drafted to serve in the Vietnam War, he enrolled at the University of Minnesota to study Music Theory and Composition under composer Dominick Argento.
In 1976, after national touring and recording experience at three Minneapolis studios, Moore decided to head to Los Angeles along with his wife and the rest of the band.
Shortly after Infinity Records went under, lead guitarist Pete McRae departed The Kats, and the four remaining band members renamed themselves The Nu-Kats.
In 1980, the Nu-Kats recorded the EP Plastic Facts, featuring the track "It's Not A Rumour", which was written by Demi and Freddy Moore.
"It's Not A Rumour" never charted, but the video would receive occasional play on MTV, especially once Demi Moore became a well-known figure after her appearances on General Hospital starting in 1982.
Moore briefly moved to the Upper West Side of Manhattan and joined local NYC band The Dates, who never recorded.
After an illness in the family brought him back to Los Angeles, Moore remained in LA and formed a new pop-influenced band called Boy.
Boy released an EP on Radioactive Records and Moore received a Screen Actors Guild/AFTRA card while portraying the small role of 'Arn' in the 1982 film Parasite, a 3-D movie which starred his wife Demi.
Freddy Moore quit the music business at around this time, although after a long layoff from performing, in 1997 he and several ex-bandmates began recording and self-releasing CDs of new material under the name The Kat Club.
