I just listened to this song on Part of Your History, very slowly, and did the best to transcribe it myself. I have been looking for the lyrics everywhere, and can't find them so here it goes:

WISH WE HAD OUR TIME AGAIN
As sung by Sam Bush and others on "Part of Your History: The Songs of John Hartford" (2006)

1. Oh the roads we ran and the folks we knew.
The risky things that we used to do.
Now it's over and I know we're through.
And I wish we had our time again
I wish we had our time again
I wish we had our time again
I wish we had our time.

2. Well, I couldn't go to sleep. Got up and made a light.
Trying to write it down in the middle of the night.
Lookin' for the words, but it won't come right.
And I wish we had our time again
I wish we had our time again
I wish we had our time again
I wish we had our time.

3. If not for love I can hardly see.
I looked at you and you looked at me.
Your memory love won't let me be,
And I wish we had our time again
I wish we had our time again
I wish we had our time again
I wish we had our time.

4. Oh me, oh my, how the years do fly.
It makes no difference and we all know why.
Dear old friends have to turn their eye.
And I wish we had our time again
I wish we had our time again
I wish we had our time again
I wish we had our time.
