In 1963, President John F. Kennedy was killed in Dallas, reputedly by Lee Harvey Oswald. The assassination became a portion of many songs, including "Six White Horses" by Tommy Cash which went to Number Four on the charts, and a verse of "Who Did They Think He Was", recorded by Conway Twitty.
In 1969, Tommy Cash released "Six White Horses". See first note from today's blog.
In 1975, "Rocky" became a chart topper for Dickey Lee. Though a great singer, and also a noted songwriter, this would be his only Number One as a performer.
In 1980, Kenny Rogers was at the top of the charts with "Lady".
In 1986, "You're Still New To Me" became a Number One for Marie Osmond, with assistance from singer/songwriter Paul Davis.
