I actually was led to this page by a reference in FYImusicnews.ca, but only after I read it did I realize this British publication, The Guardian, has been doing these kinds of articles since 2013. Some are about great Top 40 hits. Others centre on TV shows, plays and different aspects of pop culture. 

But it was the music stuff that sent me on a journey through their back pages, which are fortunately not paywalled. All feature stories few knew about some of the greatest hits of all time.

Some examples: did you know the famous guitar riff in the Kinks' "You Really Got Me" was created by an accident with a razor blade? Or that there were actually two versions of "Baby Love" released by The Supremes in 1964? And that The Four Tops hated one of their biggest hits and begged Motown's Berry Gordy not to release it?
