This is Outstanding! The package was created for WLS Chicago in 1980, and three years later it became the first jingle package to be used on KIIS-FM Los Angeles for its CHR format. The jingles deliver concise messages in a variety of styles, and always end with the classic WLS musical logo. (Historical note: WLS began to broadcast in "AM Stereo" shortly after this package was made, so a few of the jingles contained that word and were mixed in stereo- a novelty for AM stations at that time! As with all JAM packages, any cut can be mixed in stereo for today's use.)
