107.5 WBLS New York City "Disco and More" aircheck 1980

107.5 WBLS was one of the top-rated radio stations in New York City in the late 1970s, until upstart station WKTU (then on 92.3 FM) stole the show with an all-Disco format, which shot up to #1 in the ratings in 1979. WBLS responded by playing a mix of Disco and R&B music under the name "Disco and More", as heard in this 1980 cassette recording of the station.
