This is the classic ending lick as played by Earl on this tune. This is a classic ending riff, a one measure lead up and measure two has that classic "shave and a haircut" sound, but up the neck. That portion in measure 2 may be the toughest if you haven't learned a tune like Sally Goodin before. Whenever you are jamming and several people have taken leads on the tune you can use this lick after the last measure of the lead to "officially" end the song.
