Watch the Chicken in the Rain: Intro & Outro online guitar lesson by John Knowles, C.G.P. from Fingerstyle Journals
The intro and outro to "Chicken in the Rain" are both built around a lick that is so old you almost can't steal it. But you can disguise it. After I do that first pull-off, instead of playing the next two notes one-after-the-other I play them together with my ring and middle finger — a Jerry Reed move. Then the outro is just a short variation on the intro. And it just happens to fit the rhythm of the title.
