Listening to the song via the YouTube link though the speakers connected to the computer, it's a toss-up between "gal" and "here." When I listen to the M4A file that was imported from the JSP CD set into iTunes using my headphones and playing it with VLC Media Player at various speeds, I definitely hear "here."
Like you point out, the title strongly suggests, "gal," but it's possible the title was already settled on and she simply sang "here." ("Here" does fit the narrative.) Or if it was a mistake, since it was a solid take, they simply went with it rather than re-record the song. Or maybe because the song is about leaving and the singer is a gal, that was the reason for the title, regardless of the last line. --Just speculation, without any real evidence. I agree about Blind Blake's accompaniment. He created it to fit the song and the singer and did not simply throw some stock riffs together to sleepwalk through it.
As always, it's your call, John. Just because I hear something different, doesn't mean I think what you hear is wrong.
