Let's step back in time and check out the entertainment scene from 1971.
Among the year's biggest movies were Fiddler on the Roof, The French Connection and Dirty Harry.
On TV people were tuned into Marcus Welby M.D., The Flip Wilson Show and Ironside.
And during the final week of the year, these were the songs being played on the radio.
At number five on Billboard Magazine's Hot 100 was Michael Jackson with his very first solo hit, Got to be There.
In the number four spot was a song originally intended for the Carpenters. But songwriter Paul Williams gave it to Three Dog Night instead and they had another big hit with An Old Fashioned Love Song.
Don McClean was in the number three spot with a song that had hidden references to Buddy Holly, The Beatles and Bob Dylan. Of course we're talking about American Pie. In the runner up spot was Sly and the Family Stone with Family Affair. It ended up being the four and final number one for the group.
And at number one was a song about a girl with roller skates trying to attract the attention of a boy. Many thought Brand New Key by Melanie included lots of sexual innuendo in the lyrics, with phrases like "I go pretty far" and "I've been all around the world". That didn't stop radio stations from playing it and it became Melanie's biggest hit.
