"Kay" is about a taxicab driver in Nashville, Tennessee. He sold everything he owned to bring the woman he has loved and been with for years from Houston to Nashville, where she is becoming a star and moving beyond needing him. It is a song full of feelings and sadness. The song describes some of the people that he carries. Among them are soldiers from Fort Campbell who tell him that they "hate that war in Vietnam". This line has been cited as an example of the anti-war movement's presence in country music in the late 1960s.
