This is not the same as the Frank Loesser song of the same name ("Standing on the corner, watching all the girls go by.") Nor with Blue Yodel #9 (which also starts "Standing On The Corner"). It was played a few times in 1966 but never taken forward.
(1) on 27 July 1966, the Dead sang a different final verse (thanks to Chris Wallis for this):
If you ask me what I'm doing, I can't answer right
If you ask me what I'm doing, I can't answer right
Seems like nothin' ever changes, and nothing's gonna turn out right
I was standing on the corner, wondering what's become of me
I was standing on the corner, wondering what's become of me
Well things don't seem to be the way they used to seem to be
I think I'll go up on a mountain, I'll fling myself off into space
I think I'll go up on a mountain, I'll fling myself off into space
I'm not doing it because I'm desperate, I'm just trying to save some space
If you ask me what my name is, I'll just stop and scratch my head (note 1)
If you ask me what my name is, I'll just stop and scratch my head
Well they took away my name and gave me a number instead
Well all the things I used to know seem so far behind
There's a lot of new things that are running around my mind
