It's a Proverb (27:6)
"Faithful are the wounds of a friend; but the kisses of an enemy are deceitful."
So true! I love Luke's guitar solo in this song and his harmony vocal. I've always loved Luke's playing, and this is one of the most beautiful things I've ever heard come out of his guitar. Rick played along on the harmonica during practices so that he wouldn't be completely bored. I loved what he was doing so much that I made him do it for real when we recorded.
