Pat St. John (born February 12, 1951) is an American radio personality and voice-over artist. He began his radio career on Windsor, Ontario's CKLW (800 AM) in 1969 and 1970, followed by WKNR (1300 AM) in late 1970 to early 1972, followed by WRIF FM (101.1) to April 1973. Pat is best known for the 42 years he spent in the New York City market working for WPLJ, WNEW-FM, WAXQ and WCBS FM. He can now be heard on Sirius XM Radio '60s on 6 afternoons from 1:00PM to 5PM (Eastern) and also on oldies. Pat has done television voiceover work, including announcing for Dick Clark's New Year's Rockin' Eve from 2000 to 2010.
St. John is known for his conversational on-air style interspersed with bits of music trivia, along with "Collectible Cuts" from his extensive record library. Pat has been called a "walking encyclopedia" when it comes to his knowledge of music. Pat has interviewed many musicians.
St. John was born in Detroit and was raised on the music of Motown. In early 1969, at the age of 18, he landed his first gig as a radio personality on Windsor's CKLW, where he also worked for CKLW's 20/20 news doing newscasts one day a week, and part-time booth announcing on CKLW-TV Channel 9. In late 1970 he moved across the border to WKNR and was then hired in early 1972 at the ABC-owned album-oriented rock (AOR) station WRIF until 1973.
In April 1973, St. John began an almost 15-year stint at New York's WPLJ. For most of his years at WPLJ he was rated by Arbitron as the most listened to afternoon radio personality in America (source: ARB's "Drive-Time Dominators"). He survived the station's transition from AOR to top 40 in 1983, and during that era, continued his Arbitron ratings success with that same ranking.
