This is a lot of fun. Demonstrates (to me at least) just how accomplished a performer Waylon was. The song is “Loving Her Was Easier” (Kris Kristofferson).
At about 1:32, he sings “Healing as the colors in the sunshine and the shadows of her eyes.” In the middle of the phrase, you’ll notice a very very tiny smile that comes to his lips and a curious split-second look in his eye. PROBABLY because he just realized he repeated the fourth line by mistake! But covered beautifully, unnoticeably on national television with all that pressure.
The lyric that should have been sung is: “Talking of tomorrow and the money, love and time we had to spend.” Instead, he naturally went with another “ea” sound that started the previous line.
