Amazon.com description: Product Description: CKLW, based in Windsor, Ontario, was one of the most widely heard and influential Top 40 pop music radio stations of the 1960s and 1970s. It's 50,000 watt signal could be heard throughout central Canada and the Midwestern United States. In addition to reproducing its weekly charts from 1967 through 1971, an historical survey of the station is included. Like the other radio charts titles, my goal was to provide a convenient chronological compilation of weekly surveys with corrections of the considerable errors found in both the original sources and in translation to online sites. These radio charts – which exist in the public domain – can be found in a multitude of sources, including original published sheets distributed via retail outlets, mail inquiries, etc., notation of on-air broadcasts, back issues of area newspapers (where stations are located) and music trade periodicals, specialized reference books, and websites interested in historical documentation, most notably, Oldiesloon, musicradio77, and ARSA. I employed multiple sources in the compilation of each radio chart volume in order to provide the most accurate data possible.
