Should you be looking for music chart information beyond what is found on "Vancouver Top Forty
radio" or "RadioWest" Here is a site that might just fit the bill.
The site is "Old Charts.com " .. The search result reads 'Billboard is considered the foremost worldwide authority worldwide in music charts, and the rankings have gained a following among the general public." . Here is the link. http://www.old-charts.com/
The charts start at 1940 -1949 (US only). and from 1950 onward they show US and UK charts. A very interesting read.... Enjoy.
