Standard (EADGBE)
The parts with D5 and Dsus4 are all similarly flat picked, hammer-on D string.
Here is the pattern from a recording of one his live concerts, the album is slightly different.
It's time, two days away
I packed up the last and signed my name
Goodbye my cold and stolen sign
Forever's never been this long
If you're turning I'll show you where I've been
And then I'll set it straight again
Are you behind or lost and saved
Man when the lines would wash away
Of all the locks I never knew
When did you come home too
I wish I'd lasted a summer more to spend
Setting it straight again
When I go under every now and then
And try and set it straight again
