Well...........Actually Steve and Robin, "Green Pastures" is on one of my favorite albums (although I no longer have a copy), Roses in the Snow. Willie is indeed on the track playing guitar, but the duet vocal is Ricky Skaggs and the harmony is Dolly Parton! Bryan Bowers also plays autoharp on that cut.

B                         E
Trouble and trials often betray those
B                         F#
On in the weary body to stray
             B                   E
But we shall walk beside the still waters
               B       F#          B
With the good shepherd leading the way
B                                        E
Those who have strayed were sought by the master
            B                     F#
He who once gave his life for the sheep
            B                   E
Out on the mountain still he is seaching
             B    F#       B
Bringing them in forever to keep
B                              E   
Going up home to live in green pastures
               B                  F#
Where we shall live and die never more
         B                   E
Even the Lord will be in that number
             B            F#       B
When we shall reach   that heavenly shore

B                               E
We will not heed the voice of a stranger
             B               F#
For he would lead us all to despair
          B                   E
Following on with Jesuse our savior
             B          F#         B
We shall all reach that country so fair
B                              E   
Going up home to live in green pastures
               B                  F#
Where we shall live and die never more
         B                   E
Even the Lord will be in that number
             B            F#       B
When we shall reach   that heavenly shore
