Chris Fuller did this marvelous tab for Plant & Krauss' take on this great song.  
Chords are the same for Sam Phillip's (I think better) version.

Verse 1:
Cm                          G7
Strange things are happening every day
           C                 Fm   (Walking Bass F, G, G#)
I hear the music up above my head
	   G#                    Cm
Though the sight of my heart has left me again,
       G        Cm
I hear music up above

VERSE2
Cm                       G7
Secrets are written in the sky
                C                        Fm  (Walking Bass F, G, G#)
Looks like I?ve lost the love I?ve never found
          G#                      Cm
Though the sound of hope has left me again,
       G        Cm
I hear music up above

CHORUS:
C                             Em
Standing in my broken heart all night long
Am                                  F
Darkness held me like a friend when love wore off
C                                     Em
Looking for the lamb that?s hidden in the cross
    Am       F 
The finder?s lost
Dm	    C
I know I?ve loved you too much
           F            C  F  G
I?ll go on alone to get through

SOLO on Verse Chords:

VERSE 3:
Cm                           G7
I hear Rosetta singing in the night
           C                                        Fm     (Bass F, G, G#)
Echoes of light that shine like stars after they?re gone
G#                                Cm
Tonight she?s my guide as I go on alone
         G         Cm
With the music up above

SOLO on Verse Chords and on the last Cm
