Played by Dylan with the Dead on 19 July 1987 but never by the Dead themselves.
Lyrics below from the rehearsals with the Dead (thanks to Matt Schofield). They're a pretty messed up version of the 'true' lyrics.
The full lyrics as recorded on Shot Of Love are:
Heart of mine be still You can play with fire but you'll get the bill Don't let her know Don't let her know that you love her Don't be a fool, don't be blind Heart of mine
Heart of mine go back home You got no reason to wander, you got no reason to roam Don't let her see Don't let her see that you need her Don't put yourself over the line Heart of mine
Heart of mine go back where you been
Don't let her hear Don't let her hear you want her Don't let her know she's so fine Heart of mine
Heart of mine you know that she'll never be true She'll only give to others the love that she's gotten from you Don't let her know Don't let her know where you're going Don't untie the ties that bind Heart of mine
Heart of mine so malicious and so full of guile Give you an inch and you'll take a mile Don't let yourself fall Don't let yourself stumble If you can't do the time, don't do the crime Heart of mine
Heart of mine go back home
You [got no] reason to wander, no reason to roam
You let yourself down
[?]
Don't [be] let yourself down
Heart of mine
Heart of mine be still
Oh you play with fire but you'll get the bill
[Oh let] yourself down
Let yourself down where you're going
Don't be a fool, don't be blind
Heart of mine
Heart of mine so restless and bold
Give you an inch and you'll take a mile
Oh let yourself go
Let yourself know where you're going
Oh don't be a fool, don't be blind
Heart of mine
Heart of mine always [?] guile
Give you an inch and you'll take a mile
Oh [?]
Your say you know where you're going
You say you know [?] blind
Heart of mine
