K-LAW's Saturday Classic is a song that was #1 twice. Alan Jackson would take it the top of the charts in 2000, but it was originally a #1 song 33 years ago today - September 29th, 1979 - for Don Williams.

It was part of an incredible run that Don Williams had from 1974 to 1991. During that span, the man known as the 'Gentle Giant' released 46 singles. Only 4 of those didn't reach the top 10. All totaled, he has 17 #1 songs to his credit. This was the 9th of his distinguished career.

And there's a bonus in the video we found. Don and his band also perform a #1 hit from 1977. Enjoy this two-fer - 'It Must Be Love' and 'I'm Just A Country Boy'.
